4.2.1 Port 0
using port mode register 0 (PM0). When the P00 to P06 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).
Port 0 is a 7-bit I/O port with an output latch. Port 0 can be set to the input mode or output mode in 1-bit units
This port can also be used for timer I/O, serial interface data I/O, and clock I/O.
RESET input sets port 0 to input mode.
Figures 4-2 to 4-5 show block diagrams of port 0.
