R is read, and W is write.
32 ZPSE = 24-bit signed register that is transmitted as a 32-bit word with four MSBs padded with 0s and sign extended to 28 bits. Whereas 32 ZP = 28- or 24-bit signed
or unsigned register that is transmitted as a 32-bit word with four or eight MSBs, respectively, padded with 0s.
U is unsigned register, and S is signed register in twos complement format.
R is read, and W is write.
U is unsigned register, and S is signed register in twos complement format.
