This read-only bitfield is reserved and always has the value zero.
This is the low byte of the 16-bit CRC register. Normally, a write to CRCL will cause the CRC generator to
begin clocking through the 16-bit CRC generator. As a special case, if a write to CRCH has occurred
previously, a subsequent write to CRCL will load the value in the register as the low byte of a 16-bit seed
value directly into bits 7-0 of the shift register in the CRC generator. A read of CRCL will read bits 7-0 of
the current CRC calculation result directly out of the shift register in the CRC generator.
This read-only bitfield is reserved and always has the value zero.
This register is used to transpose data, converting from LSb to MSb (or vice-versa). The byte to be
transposed should be first written to TRANSPOSE and then subsequent reads from TRANSPOSE will
return the transposed value of the last written byte (bit 7 becomes bit 0, bit 6 becomes bit 1, and so forth).
