PMCn - Port mode control register
The PMCn register specifies whether the individual pins of port group n are in
port mode or in alternative 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.

PMCn register contents
PFCn - Port function control register
If a pin is in alternative mode and serves as an output pin (PMn.PMnm = 0)
some pins offer two output functions ALT1-OUT and ALT2-OUT.
The 8-bit PFCn register specifies which output function of a pin is to be used.
This register can be read/written in 8-bit and 1-bit units.
see “Port Group Configuration“ on page 56
PFC0: 20
other PFCn: 00
This register is initialized by any reset.
