2.3.18.14
These registers are used to specify the color for the overscan function. This function can be used to create
custom screen borders (see Section 2.3.11). They are not initialized and can be written to or read from by
the MPU at any time. The register formats for the overscan-color registers are shown below.

Values 00 (hex) to FF (hex) can be written into the overscan color registers.

CRC LSB and MSB Registers (Index 3C – 3D hex)
These registers are used to read the result of the 16-bit CRC calculation (see Section 2.3.13). They are not
initialized and can be read by the MPU at any time. Note, however, that they are only updated on the rising
edge of the second horizontal sync during vertical retrace.
CRC LSB and CRC MSB are cascaded to form a 16-bit CRC calculation remainder.

2.3.18.16
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 2.3.13). The register is not initialized and can be written to by the MPU at any time. The CRC
control register format is shown below.
