Registers
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<3:0> > 7, or
16 when PLEN<3:0>
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
Unimplemented: Read as ‘0’
CRCGO: Start CRC bit
1 = Start CRC serial shifter
0 = CRC serial shifter turned off
PLEN<3:0>: Polynomial Length bits
Denotes the length of the polynomial to be generated minus 1.
