4.3.1 Port mode registers (PMxx)
These registers specify input or output mode for the port in 1-bit units.
These registers can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets these registers to FFH.
When port pins are used as alternate-function pins, set the port mode register by referencing 4.5 Settings of Port
Mode Register and Output Latch When Using Alternate Function.
