Typical exposure times
6.6.5 Asynchronous operation, shutter control by pulse width
This operating mode is selected with register 6:
:r6[7..4]
= 0xb
An external trigger signal (EXP input) with selectable polarity can
start and stop exposure. Exposure time is then dependent on the
duration of the trigger signal., or on the setting of the exposure
timer. The least 4 significant bits of r6 define exposure time.
6.6.6 Asynchronous operation, shutter control by timer
This operating mode is selected with register 6:
:r6[7..4]
= 0xb
The asynchronous exposure time is dependent on the four least
significant bits of r6 and on the frequency of the sensor clock.
