30.3.10.18 CRCACC SFR Description

The CRCACC, CRC Accumulator, reports the LFSR state which changes during the calculation for each byte shifted in. Section 30.3.10.21 CRCSUM SFR Description defines how the compare equation uses CRCACC when the CRC calculation completes. PLEN32 controls the accumulator size. When selecting CRC-16, bit 16 and above are not used.
