P30 to P38 (Port 3)
Port 3 is a 9-bit I/O port for which input and output can be set in 1-bit units.
In addition to I/O port pins, P30 to P38 can also be used as external interrupt request inputs, serial
interface I/O, CAN I/F I/O and timer/counter I/O in the control mode. The port/control mode can be
selected for each bit, and the pin valid edge for P31 and P37 is specified by the INTR3 and INTF3
registers.
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 3 (PU3, PD3).
(a) Port mode
P30 to P38 can be set to input or output in 1-bit units using port mode register 3 (PM3).
(b) Control mode
P30 to P38 can be set to control modes in 1-bit units using port mode control register 3 (PMC3),
port mode function register 3 (PFC3) and port mode function expand register 3 (PFCE3)
