RBS[7:6] – rsvd (RBS[7:6] = 01)
RBS[5:0] – red channel bias value. 
This value defines the fine tune adjustment for the red tint in the white balance control. This reg-
ister is the manual control portion of the AWB control
Note: 
This function is not available on the OV7410P/OV7411P Image Sensor.

Version
MIDH[7:0] – manufacture ID high byte
MIDL[7:0] – manufacture ID low byte
AEC[7:0] – Manual exposure setting. “00” = lowest, 82 = Highest
COMA[7] - CEXP, “0” selects central exposure
COMA[6:4] - rsvd
COMA[3] - GAMMA, “1” selects gamma = 0.45, “0” select gamma=1.0
COMA[2] - AGCEN, “1” enables auto gain control
COMA[1] - AWBEN “1” enables auto white balance
*
COMA[0] - AEC enable. If AEC is enabled, the AEC register (Reg. 13) is updated automatically. 
If AEC is disabled, AEC register remains unchanged.

COMB[7] - SRST, “1” initiates soft reset. Initiate soft reset. All registers are set to default values 
and chip is reset to known state and resumes normal operation. This bit is automatically 
cleared after reset.
COMB[6]] - MIRR, “1” selects mirror image
COMB[5]] - VSFR, “1” enables frame sync output to VSYNC (pin 32), “0” enables field sync 
ouput to VSYNC
COMB[4]] - BKLT, “1” selects backlight exposure mode
COMB[3]] - FREX, “1” disables the update of exposure and gain value
COMB[2] - HGAIN. Automatic Gain Control (AGC) gain range selection. See COME[6] (G2X), 
below.
“0” - select normal AGC range (1X <-> 4X)
“1” - select expanded AGC range (1X -> 8X)
