4.2.1 Port 0
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).
timer I/O can be assigned to P00 of the 78K0/KA2-L (25-pin products) by setting the port alternate switch control register
(MUXSEL).

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 port
This port can also be used for timer I/O, external interrupt request input, and chip select input of serial interface. The
Reset signal generation sets port 0 to input mode.
Figures 4-1 to 4-3 show block diagrams of port 0.
