##### How to use this driver #####
==============================================================================
[..]
The FMPSMBUS HAL driver can be used as follows:
(#) Declare a FMPSMBUS_HandleTypeDef handle structure, for example:
FMPSMBUS_HandleTypeDef hfmpsmbus;
(#)Initialize the FMPSMBUS low level resources by implementing the HAL_FMPSMBUS_MspInit() API:
(##) Enable the FMPSMBUSx interface clock
(##) FMPSMBUS pins configuration
(+++) Enable the clock for the FMPSMBUS GPIOs
(+++) Configure FMPSMBUS pins as alternate function open-drain
(##) NVIC configuration if you need to use interrupt process
(+++) Configure the FMPSMBUSx interrupt priority
(+++) Enable the NVIC FMPSMBUS IRQ Channel
(#) Configure the Communication Clock Timing, Bus Timeout, Own Address1, Master Addressing mode,
Dual Addressing mode, Own Address2, Own Address2 Mask, General call, Nostretch mode,
Peripheral mode and Packet Error Check mode in the hfmpsmbus Init structure.
(#) Initialize the FMPSMBUS registers by calling the HAL_FMPSMBUS_Init() API:
(++) These API's configures also the low level Hardware GPIO, CLOCK, CORTEX...etc)
by calling the customized HAL_FMPSMBUS_MspInit(&hfmpsmbus) API.
(#) To check if target device is ready for communication, use the function HAL_FMPSMBUS_IsDeviceReady()
(#) For FMPSMBUS IO operations, only one mode of operations is available within this driver
*** Interrupt mode IO operation ***
===================================
[..]
(+) Transmit in master/host FMPSMBUS mode an amount of data in non-blocking mode
using HAL_FMPSMBUS_Master_Transmit_IT()
(++) At transmission end of transfer HAL_FMPSMBUS_MasterTxCpltCallback() is executed and users can
add their own code by customization of function pointer HAL_FMPSMBUS_MasterTxCpltCallback()
(+) Receive in master/host FMPSMBUS mode an amount of data in non-blocking mode
using HAL_FMPSMBUS_Master_Receive_IT()
(++) At reception end of transfer HAL_FMPSMBUS_MasterRxCpltCallback() is executed and users can
add their own code by customization of function pointer HAL_FMPSMBUS_MasterRxCpltCallback()
(+) Abort a master/host FMPSMBUS process communication with Interrupt using HAL_FMPSMBUS_Master_Abort_IT()
(++) The associated previous transfer callback is called at the end of abort process
(++) mean HAL_FMPSMBUS_MasterTxCpltCallback() in case of previous state was master transmit
(++) mean HAL_FMPSMBUS_MasterRxCpltCallback() in case of previous state was master receive
(+) Enable/disable the Address listen mode in slave/device or host/slave FMPSMBUS mode
using HAL_FMPSMBUS_EnableListen_IT() HAL_FMPSMBUS_DisableListen_IT()
(++) When address slave/device FMPSMBUS match, HAL_FMPSMBUS_AddrCallback() is executed and users can
add their own code to check the Address Match Code and the transmission direction
request by master/host (Write/Read).
(++) At Listen mode end HAL_FMPSMBUS_ListenCpltCallback() is executed and users can
add their own code by customization of function pointer HAL_FMPSMBUS_ListenCpltCallback()
(+) Transmit in slave/device FMPSMBUS mode an amount of data in non-blocking mode
using HAL_FMPSMBUS_Slave_Transmit_IT()
(++) At transmission end of transfer HAL_FMPSMBUS_SlaveTxCpltCallback() is executed and users can
add their own code by customization of function pointer HAL_FMPSMBUS_SlaveTxCpltCallback()
(+) Receive in slave/device FMPSMBUS mode an amount of data in non-blocking mode
using HAL_FMPSMBUS_Slave_Receive_IT()
(++) At reception end of transfer HAL_FMPSMBUS_SlaveRxCpltCallback() is executed and users can
add their own code by customization of function pointer HAL_FMPSMBUS_SlaveRxCpltCallback()
(+) Enable/Disable the FMPSMBUS alert mode using
HAL_FMPSMBUS_EnableAlert_IT() or HAL_FMPSMBUS_DisableAlert_IT()
(++) When FMPSMBUS Alert is generated HAL_FMPSMBUS_ErrorCallback() is executed and users can
add their own code by customization of function pointer HAL_FMPSMBUS_ErrorCallback()
to check the Alert Error Code using function HAL_FMPSMBUS_GetError()
(+) Get HAL state machine or error values using HAL_FMPSMBUS_GetState() or HAL_FMPSMBUS_GetError()
(+) In case of transfer Error, HAL_FMPSMBUS_ErrorCallback() function is executed and users can
add their own code by customization of function pointer HAL_FMPSMBUS_ErrorCallback()
to check the Error Code using function HAL_FMPSMBUS_GetError()
*** FMPSMBUS HAL driver macros list ***
==================================
[..]
Below the list of most used macros in FMPSMBUS HAL driver.
(+) __HAL_FMPSMBUS_ENABLE: Enable the FMPSMBUS peripheral
(+) __HAL_FMPSMBUS_DISABLE: Disable the FMPSMBUS peripheral
(+) __HAL_FMPSMBUS_GET_FLAG: Check whether the specified FMPSMBUS flag is set or not
(+) __HAL_FMPSMBUS_CLEAR_FLAG: Clear the specified FMPSMBUS pending flag
(+) __HAL_FMPSMBUS_ENABLE_IT: Enable the specified FMPSMBUS interrupt
(+) __HAL_FMPSMBUS_DISABLE_IT: Disable the specified FMPSMBUS interrupt
*** Callback registration ***
=============================================
[..]
The compilation flag USE_HAL_FMPSMBUS_REGISTER_CALLBACKS when set to 1
allows the user to configure dynamically the driver callbacks.
Use Functions HAL_FMPSMBUS_RegisterCallback() or HAL_FMPSMBUS_RegisterAddrCallback()
to register an interrupt callback.
[..]
Function HAL_FMPSMBUS_RegisterCallback() allows to register following callbacks:
(+) MasterTxCpltCallback : callback for Master transmission end of transfer.
(+) MasterRxCpltCallback : callback for Master reception end of transfer.
(+) SlaveTxCpltCallback : callback for Slave transmission end of transfer.
(+) SlaveRxCpltCallback : callback for Slave reception end of transfer.
(+) ListenCpltCallback : callback for end of listen mode.
(+) ErrorCallback : callback for error detection.
(+) MspInitCallback : callback for Msp Init.
(+) MspDeInitCallback : callback for Msp DeInit.
This function takes as parameters the HAL peripheral handle, the Callback ID
and a pointer to the user callback function.
[..]
For specific callback AddrCallback use dedicated register callbacks : HAL_FMPSMBUS_RegisterAddrCallback.
[..]
Use function HAL_FMPSMBUS_UnRegisterCallback to reset a callback to the default
weak function.
HAL_FMPSMBUS_UnRegisterCallback takes as parameters the HAL peripheral handle,
and the Callback ID.
This function allows to reset following callbacks:
(+) MasterTxCpltCallback : callback for Master transmission end of transfer.
(+) MasterRxCpltCallback : callback for Master reception end of transfer.
(+) SlaveTxCpltCallback : callback for Slave transmission end of transfer.
(+) SlaveRxCpltCallback : callback for Slave reception end of transfer.
(+) ListenCpltCallback : callback for end of listen mode.
(+) ErrorCallback : callback for error detection.
(+) MspInitCallback : callback for Msp Init.
(+) MspDeInitCallback : callback for Msp DeInit.
[..]
For callback AddrCallback use dedicated register callbacks : HAL_FMPSMBUS_UnRegisterAddrCallback.
[..]
By default, after the HAL_FMPSMBUS_Init() and when the state is HAL_FMPI2C_STATE_RESET
all callbacks are set to the corresponding weak functions:
examples HAL_FMPSMBUS_MasterTxCpltCallback(), HAL_FMPSMBUS_MasterRxCpltCallback().
Exception done for MspInit and MspDeInit functions that are
reset to the legacy weak functions in the HAL_FMPSMBUS_Init()/ HAL_FMPSMBUS_DeInit() only when
these callbacks are null (not registered beforehand).
If MspInit or MspDeInit are not null, the HAL_FMPSMBUS_Init()/ HAL_FMPSMBUS_DeInit()
keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
[..]
Callbacks can be registered/unregistered in HAL_FMPI2C_STATE_READY state only.
Exception done MspInit/MspDeInit functions that can be registered/unregistered
in HAL_FMPI2C_STATE_READY or HAL_FMPI2C_STATE_RESET state,
thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
Then, the user first registers the MspInit/MspDeInit user callbacks
using HAL_FMPSMBUS_RegisterCallback() before calling HAL_FMPSMBUS_DeInit()
or HAL_FMPSMBUS_Init() function.
[..]
When the compilation flag USE_HAL_FMPSMBUS_REGISTER_CALLBACKS is set to 0 or
not defined, the callback registration feature is not available and all callbacks
are set to the corresponding weak functions.
[..]

This subsection provides a set of functions allowing to manage the FMPSMBUS data
transfers.
(#) Blocking mode function to check if device is ready for usage is :
(++) HAL_FMPSMBUS_IsDeviceReady()
(#) There is only one mode of transfer:
(++) Non-Blocking mode : The communication is performed using Interrupts.
These functions return the status of the transfer startup.
The end of the data processing will be indicated through the
dedicated FMPSMBUS IRQ when using Interrupt mode.
(#) Non-Blocking mode functions with Interrupt are :
(++) HAL_FMPSMBUS_Master_Transmit_IT()
(++) HAL_FMPSMBUS_Master_Receive_IT()
(++) HAL_FMPSMBUS_Slave_Transmit_IT()
(++) HAL_FMPSMBUS_Slave_Receive_IT()
(++) HAL_FMPSMBUS_EnableListen_IT() or alias HAL_FMPSMBUS_EnableListen_IT()
(++) HAL_FMPSMBUS_DisableListen_IT()
(++) HAL_FMPSMBUS_EnableAlert_IT()
(++) HAL_FMPSMBUS_DisableAlert_IT()
(#) A set of Transfer Complete Callbacks are provided in non-Blocking mode:
(++) HAL_FMPSMBUS_MasterTxCpltCallback()
(++) HAL_FMPSMBUS_MasterRxCpltCallback()
