ENABLE_COLOR_CRC: 
Enables the CRC calculations. After being enabled for the first 
time, you need to wait for two VBLANK events for a valid CRC result. After that, a CRC 
will be generated each frame. 
0 = CRC Calculations are disabled 
1 = CRC Calculations are enabled

EXPECTED_CRC_VALUE: 
Expected CRC Value for Color Channel. This is the value used 
to generate the CRC error status and interrupt. Resultant CRC values are compared to 
this register after the completion of a CRC calculation. Status indications are in the 
PIPEASTAT register.
