0x16 vsize (vsize = register-value * 16)

0x17 bit 0 toggle compression quality (according to sn9c102 driver)
|

0x18 bit 7 enables compression, bit 4-5 set image down scaling:

00 scale 1, 01 scale 1/2, 10, scale 1/4
|
||
|
|
0x19 high-nibble is sensor clock divider, changes exposure on sensors which
|

use a clock generated by the bridge. Some sensors have their own clock.
