6.49 Channel 2 Color Calibration 3B (CH2_CAL3B)
– Address 123
6.50 CRC Memory Tag 3B(CRC_MTAG3B)
– Address 124
CRC Memory Tag 3B register used by the color control system. To activate the use of this register the SET_3B
bit must be programmed to ‘1’ (see "Channel 1 Color Calibration 3B (CH1_CAL3B) – Address 122" on page 52).
The CRC value is obtained by computing the CRC value for the registers at address 122 and 123.

Number Name Description
[7] SET_3B
Configures the color control system to use the color calibration values in
memory tag 3B.
0 = Disables the use of memory tag 3B
1 = Enables the use of memory tag 3B (Takes priority over SET_3A=1)

[5:0] CH1_CAL3B[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_CAL3B[5:0]31. The calibration current gain is given by:
