Chapter 18: LPC43xx Serial GPIO (SGPIO)
18.6.4 Slice data registers (REG0 to 15)
Each register contains the data for one slice: REG0 to REG15 contain data for slice A
(register 0) to slice P (register 15).
At an active shift clock data is right shifted; captured data is shifted in at bit 31, and
register data is shifted out from bit 0.
