Table 23. Tristate Control Register
The Programable Bias Generator Control register; Ta-
ble 24 can be used by the user to vary the power con-
sumption of the White Balance PGA (PGAWB),
Exposure gain PGA A (PGAEXPa), Exposure gain PGA
B (PGEXPb), Frame Rate Clamp (FRC), Column Offset
DOVA (COL_DOVA), Global offset DOVA (DOVE) and/
or the Analog to Digital converter (A2D) between half an
full current (power) consumption.
In order for this Register to be used, the pbg bit of the
Power Configuration Register; Table 21 has to be en-
abled.
