6.45 Channel 1 Color Calibration 3A (CH1_CAL3A) – Address 119
6.46 Channel 2 Color Calibration 3A (CH2_CAL3A)
– Address 120
6.47 CRC Memory Tag 3A (CRC_MTAG3A)
– Address 121
CRC Memory Tag 3A register used by the color control system. To activate the use of this register the SET_3A
bit must be programmed to ‘1’ (see "Channel 1 Color Calibration 3A (CH1_CAL3A) – Address 119" on page 51).
The CRC value is obtained by computing the CRC value for the registers at address 119 and 120.

Number Name Description
[7] SET_3A
Configures the color control system to use the color calibration values in
memory tag 3A.
0 = Disables the use of memory tag 3A
1 = Enables the use of memory tag 3A
[6] - Reserved
[5:0] CH1_CAL3A[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_CAL3A[5:0]31. The calibration current gain is given by:
