Register Description (continued)
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.
1 = Use horizontal blanking context B, Reg0x05.
0 = Use horizontal blanking context A, Reg0x07.
1 = Use vertical blanking context B, Reg0x06.
0 = Use vertical blanking context A, Reg0x08.
Enable LED flash. Same physical register as Reg0x23[8].
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.
Enable Xenon flash. Same physical register as Reg0x23[13].
Setting this bit will cause the sensor to abandon the current
frame and start resetting the first row. Same physical
register as Reg0x0D[1].
