6.51 Channel 1 Color Calibration 3C (CH1_CAL3C) – Address 125
6.52 Channel 2 Color Calibration 3C (CH2_CAL3C)
– Address 126
6.53 CRC Memory Tag 3C (CRC_MTAG3C)
– Address 127
CRC Memory Tag 3C register used by the color control system. To activate the use of this register, the SET_3C
bit must be programmed to ‘1’ (see "Channel 1 Color Calibration 3C (CH1_CAL3C) – Address 125" on page 53).
The CRC value is obtained by computing the CRC value for the registers at address 125 and 126.

Number Name Description
[7] SET_3C
Configures the color control system to use the color calibration values in
memory tag 3C.
0 = Disables the use of memory tag 3C
1 = Enables the use of memory tag 3C (Takes priority over SET_3B=1)

[5:0] CH1_CAL3C[5:0]
Channel 1 color control system calibration value that scales the current of
channel 1 within ±15%. The value is a two’s complement integer in the range
of -32CH1_CAL3C[5:0]31. The calibration current gain is given by:
