CRC LSB and MSB Registers
These registers are used to read the result of the 16–bit CRC calculation (see section 2.9). They are not
initialized and may be read from by the MPU at any time. One must note, however, that they are only updated
on the rising edge of the second HSYNC during vertical retrace.
CRCLSB and CRCMSB are cascaded to form a 16–bit CRC calculation remainder.

CRC Control Register
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 2.9). The register is not initialized and maybe written to by the MPU at any time. The CRC
Control register data format is shown below.
