4.2.1 Port 0
port mode register 0 (PM0). When the P00 to P02 pins are used as an input port, use of an on-chip pull-up resistor
can be specified in 1-bit units by pull-up resistor option register 0 (PU0).
P00/TI000/INTP0
P01/TO00/TI010
Port 0 is an I/O port with an output latch. Port 0 can be set to the input mode or output mode in 1-bit units using
This port can also be used for timer I/O and external interrupt request input.
Reset signal generation sets port 0 to input mode.
Figures 4-1 to 4-3 show block diagrams of port 0.
