(2) Port registers (P2 to P4)
(3) Port mode control register 2 (PMC2) (
These registers are used to write data to be output from the corresponding port pin to an external device
connected to the chip.
When a port register is read, the pin level is read in the input mode, and the value of the output latch of the
port is read in the output mode.
P20 to P23, P32, P40 and P43 are set by using a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets these registers to 00H.
This register specifies the port/alternate function (except the A/D converter function) mode or the 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.
Reset signal generation sets PMC2 to 00H.
Note Because P34 is read-only, its reset value is undefined.
