4.2.4 Port 3
using port mode register 3 (PM3). When 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 3 (PU3).

Port 3 is a 4-bit I/O port with an output latch. Port 3 can be set to the input mode or output mode in 1-bit units
This port can also be used for external interrupt request input and timer I/O.
Reset signal generation sets port 3 to input mode.
Figures 4-10 and 4-11 show block diagrams of port 3.
