Table 24 and Table 25 show the available registers (fields)
to program the desired exposure time and gain settings.
Settings 199[1:0] and 199[15:14] should remain unchanged.

Description
201
0x0000 Exposure time
Rolling shutter: granularity = lines
Global shutter: granularity defined by
’Mult Timer’ (register 199).
199
0x0001 Mult Timer (global shutter only)
Defines granularity of exposure and
reset length.
unit = 1/68 MHz for normal ROT mode
200
0x0000 Reset length or Frame Length (global
shutter only)
Granularity defined by ’Mult Timer’
(register 199)

Postpone gain update by one frame
when ‘1’ to compensate for exposure
time updates latency.

Digital Gain, 5.7 unsigned representation
(5 bits before decimal point, 7 bits for
fractional part). Maximum gain is 31.992
