4.2.6 Port 5
using port mode register 5 (PM5). When the P50 to P55 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 5 (PU5).
Port 5 is an 6-bit I/O port with an output latch. Port 5 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.
Reset signal generation sets port 5 to input mode.
Figures 4-18 and 4-19 show block diagrams of port 5.
