6.48 Channel 1 Color Calibration 3B (CH1_CAL3B) – Address 122

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.

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)
