CRC Remainder LSB and MSB Registers (Index: 0x3C–0x3D, Access: Read
Only, Default: Uninitialized)
These registers are used to read the result of the 16-bit CRC calculation (see Section 2.13.1). They are not
initialized and can be read by the MPU at any time. The CRC is updated when two consecutive HSYNC
pulses are detected while BLANK is active (vertical retrace). The CRC is only calculated on the active screen
area, i.e., active blank stops the calculation. One complete vertical screen must be completed to generate
a valid CRC.

2.16.10 CRC Bit Select Register (Index: 0x3E, Access: Write Only,
Default: Uninitialized)
This write-only register is used to specify which of the 24 DAC data lines the 16-bit CRC should be calculated
on (see Section 2.13.1). The register is not initialized and can be written to by the MPU at any time. The CRC
bit select register data format is shown below. Values from 0 to 23 (0x17) may be written into the register
to select the appropriate data line.
