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:
[5:0]
CH1_CAL3A[5:0]
1 + CH1_CAL3A[5:0] 0.00488

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.
