Port Name
Table 4-3. Setting of Port Mode Register, Port Register (Output Latch), and Port Mode Control Register
This register specifies the port mode or A/D converter mode.
Each bit of the PMC2 register corresponds to each pin of port 2 and can be specified in 1-bit units.
PMC2 is set by using a 1-bit or 8-bit memory manipulation instruction.
Generation of reset signal sets PMC2 to 00H.
Caution When PMC20 to PMC23 are set to 1, the P20/ANI0 to P23/ANI3 pins cannot be used as port
