PMn - Port mode register
The PMn register specifies whether the individual pins of the port group n are
in input mode or in output mode.
For port groups with up to eight ports, this is an 8-bit register. For port groups
with up to 16 ports, this is a 16-bit register.
This register can be read/written in 8-bit and 1-bit units.
16-bit registers can also be read/written in 16-bit units.
