(1) Port mode registers (PM0, PM1, PM3 to PM9, PM12, PM13)
5-5.
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 except for PM13. PM13 is set to FEH.
When port pins are used as alternate-function pins, set the port mode register and output latch as shown in Table
