12.3 - PORT0
The two 8-bit ports P0H and P0L represent the
higher and lower part of PORT0, respectively.
Both halves of PORT0 can be written (via a PEC
transfer) without effecting the other half.
P0L (FF00h / 80h)
P0H (FF02h / 81h)
DP0L (F100h / 80h)
DP0H (F102h / 81h)
P0X.y
DP0X.y

Port Data Register P0H or P0L Bit y
Port Direction Register DP0H or DP0L Bit y
DP0X.y = 0: Port line P0X.y is an input (high-impedance)
DP0X.y = 1: Port line P0X.y is an output
