(2) Port n mode register (PMn)
(3) Port n mode control register (PMCn)
(4) Port n function control register (PFCn)
The PMn register specifies the input or output mode of the corresponding port pin.
Each bit of this register corresponds to one pin of port n, and the input or output mode can be specified in 1-bit
units.
The PMCn register specifies the port mode or alternate function.
Each bit of this register corresponds to one pin of port n, and the mode of the port can be specified in 1-bit
units.
The PFCn register specifies the alternate function of a port pin to be used if the pin has two alternate functions.
Each bit of this register corresponds to one pin of port n, and the alternate function of a port pin can be
specified in 1-bit units.
