CRCEN: CRC Enable bit
1 = Enables module
0 = Disables module; all state machines, pointers and CRCWDAT/CRCDATH registers reset; other
Unimplemented: Read as ‘0’
CSIDL: CRC Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
VWORD<4:0>: Pointer Value bits
Indicates the number of valid words in the FIFO. Has a maximum value of 8 when PLEN<4:0>  7 or 16
when PLEN<4:0>
CRCFUL: FIFO Full bit
1 = FIFO is full
0 = FIFO is not full
CRCMPT: FIFO Empty bit
1 = FIFO is empty
0 = FIFO is not empty
CRCISEL: CRC Interrupt Selection bit
1 = Interrupt on FIFO is empty; the final word of data is still shifting through the CRC
0 = Interrupt on shift is complete and results are ready
CRCGO: Start CRC bit
1 = Start CRC serial shifter
0 = CRC serial shifter is turned off
LENDIAN: Data Shift Direction Select bit
1 = Data word is shifted into the CRC, starting with the LSb (little endian)
0 = Data word is shifted into the CRC, starting with the MSb (big endian)
Unimplemented: Read as ‘0’
