Time base
Corresponding to IIDC, exposure time is set via a 12-bit value in the corre-
sponding register (SHUTTER_INQ [51Ch] and SHUTTER [81Ch]).
This means that you can enter a value in the range of 1 to 4095.
Oscar cameras use a time base which is multiplied by the shutter register
value. This multiplier is configured as the time base via the TIMEBASE regis-
ter.
The time base IDs 0-9 are in bits 28 to 31. See Table 86: Time base ID on
page 184.
Default time base is 20 µs: This means that the integration time can be
changed in 20 µs increments with the shutter control.
