(5)
P50 to P55 (Port 5)
Port 5 is a 6-bit I/O port for which input and output can be set in 1-bit units.
In addition to I/O port pins, P50 to P55 can also be used as timer/counter I/O and CSI3 in the con-
trol mode. The port/control mode can be selected for each bit.
An on-chip pull-up and Pull-down resistor can be specified for use in 1-bit units using pull-up/ pull-
down resistor option register 5 (PU5, PD5).
(a) Port mode
P50 to P55 can be set to input or output in 1-bit units using port mode register 5 (PM5).
(b) Control mode
P50 to P55 can be set to control modes in 1-bit units using port mode control register 5 (PMC5)
and port mode function register 5 (PFC5).
