Note 1:
CRCAPP: CRC Append Mode bit
1 = The DMA transfers data from the source into the CRC but NOT to the destination. When a block transfer
0 = The DMA transfers data from the source through the CRC obeying WBO as it writes the data to the
CRCTYP: CRC Type Selection bit
1 = The CRC module will calculate an IP header checksum
0 = The CRC module will calculate a LFSR CRC
Unimplemented: Read as ‘0’
CRCCH<2:0>: CRC Channel Select bits
111 = CRC is assigned to Channel 7
110 = CRC is assigned to Channel 6
101 = CRC is assigned to Channel 5
100 = CRC is assigned to Channel 4
011 = CRC is assigned to Channel 3
010 = CRC is assigned to Channel 2
001 = CRC is assigned to Channel 1
000 = CRC is assigned to Channel 0
When WBO = 1, unaligned transfers are not supported and the CRCAPP bit cannot be set.
