Description: These files allow asserting system power cycling, switching
|
|
power supply units on and off and system's main power domain
|
|
shutdown.
|
|
Expected behavior:
|
|
When pwr_cycle is written 1: auxiliary power domain will go
|
|
down and after short period (about 1 second) up.
|
|
When psu1_on or psu2_on is written 1, related unit will be
|
|
disconnected from the power source, when written 0 - connected.
|
|
If both are written 1 - power supplies main power domain will
|
|
go down.
|
|
When pwr_down is written 1, system's main power domain will go
|
|
down.
|
|
|
|
The files are write only.
