12.3.6.28
I²C Address: h092+n(Low); CPU Address: h0570+2n(Low) (n = logical port number)
I²C Address: h09A+n(High); CPU Address: h0571+2n(High)
Accessed by CPU and I²C (R/W)
(Default 00) This register is duplicated eight times from PORT 0 through PORT 7 and allows the CPU to define
eight separate ports.
