4.2.1 Port 0
mode register 0 (PM0). When the P00 and P01 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/TI00
P01/TO00
Port 0 is I/O port with an output latch. Port 0 can be set to the input mode or output mode in 1-bit units using port
This port can also be used for timer I/O.
Reset signal generation sets port 0 to input mode.
Figures 4-1 and 4-2 shows block diagrams of port 0.

To use P01/TO00 as a general-purpose port, set bit 0 (TO00) of timer output register 0 (TO0)
and bit 0 (TOE00) of timer output enable register 0 (TOE0) to “0”, which is the same as their
default status setting.
To use the crest interrupt signal (INTTMM0) and valley interrupt signal (INTTMV0) of the
inverter control function, output from timer channel 0 must be enabled (by setting TOE00 to
1).
Therefore, P01/TO00 cannot be used as a general-purpose output port.
