CHAPTER 2 PIN FUNCTIONS

Port 0
6-bit input-only port
P00 is the input port that indicates the status of the NMI pin. The level of
the NMI pin can be read by reading the P0.P00 bit. When a valid edge is
input, the port functions as an NMI input.
Port 1
3-bit I/O port
Input or output can be specified in 1-bit units
Port 2
8-bit I/O port
Input or output can be specified in 1-bit units
Port 3
5-bit I/O port
Input or output can be specified in 1-bit units
Port 4
