The function of the above three sets of registers are the same. However, they correspond to different RHDLC.
BITENn:
= 0: The data is not extracted from the corresponding bit.
= 1: The data is extracted from the corresponding bit of the assigned channel.
These bits are invalid when the EVEN bit and the ODD bit are both logic 0.
The BITEN[7] bit corresponds to the first bit (MSB) of the selected channel.
