Selection of I/O mode of Pmn pin (m = 2, 3, 4, or 12; n = 0 to 5)
0
Output mode (output buffer ON)
1
Input mode (output buffer OFF)
(2) Port registers (P2, P3, P4, P12, P13)
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, P30, P31, P34, P40 to P45, P121 to P123, and P130 are set by using a 1-bit or 8-bit memory
manipulation instruction.
Reset signal generation sets these registers to 00H.
