Green2
Calibration
Value
Analog calibration offset for green2 pixels, represented as a
two’s complement signed 8-bit value (if [8] is clear, the offset
is positive and the magnitude is given by [7:0]. If [8] is set,
the offset is negative and the magnitude is given by Not
([7:0]) + 1). If Reg0x60[0] = 0, this register is read-only and
returns the current value computed by the black level
calibration algorithm. If Reg0x60[0] = 1, this register is read/
write and can be used to set the calibration offset manually.
Green2 pixels share rows with blue pixels.

Horizontal
Blanking Select 0 = Use horizontal blanking context A, Reg0x07.
Vertical 1 = Use vertical blanking context B, Reg0x06.
Blanking Select 0 = Use vertical blanking context A, Reg0x08.
1 = Use horizontal blanking context B, Reg0x05.
LED Flash
Enable
Enable LED flash. Same physical register as Reg0x23[8].

Read Mode
Select
1 = Use read mode context B, Reg0x20.
0 = Use read mode context A, Reg0x21.
Note that bits only found in read mode, context B register,
will always be taken from that register.

Restart
Setting this bit will cause the sensor to abandon the current
frame and start resetting the first row. Same physical
register as Reg0x0D[1].
