4.2.1 Port 0
using port 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).

Port 0 is a 2-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.
Reset signal generation sets port 0 to input mode.
Figures 4-2 and 4-3 show block diagrams of port 0.
