(1) Port mode registers (PM0, PM2, PM3, PM4, PM12)
These registers are used to set the corresponding port to the input or output mode in 1-bit units.
Each port mode register can be set by a 1-bit or 8-bit memory manipulation instruction.
Generation of reset signal sets these registers to FFH.
When a port pin is used as an alternate-function pin, set its port mode register and output latch as shown in
Table 4-3.
Caution Because P30, P31, and P43 are also used as external interrupt pins, the corresponding
