Reset.
Setting this bit to 1 will reset the CRC module and set the CRC results SFR to
the seed value as specified by the SEED bit. The CRC module should be reset
before starting a new CRC.
This bit is self-clearing.
DMA Mode.
Setting this bit will configure the CRC1 module for DMA mode.
Once a DMA channel has been configured to use accept peripheral requests
from CRC1, setting this bit will initiate a DMA CRC operation.
This bit should be cleared after each CRC DMA transfer.
Flip.
Setting this bit will flip the contents of the 16-bit CRC result SFRs.
(CRC0OUTH:CRC0OUTL)
This operation is normally performed only on the final CRC results.
This bit should be cleared before starting a new CRC computation.
Invert.
Setting this bit will invert the contents of the 16-bit CRC result SFR.
(CRC0OUTH:CRC0OUTL)
This operation is normally performed only on the final CRC results.
This bit should be cleared before starting a new CRC computation.
Seed Polarity.
If this bit is zero, a seed value or 0x0000 will be used.
If this bit is 1, a seed value of 0xFFFF will be used.
This bit should be set before setting the RST bit.
