This function becomes valid when output from PWM0 – PWM2 are
disabled.
This is an output pin of 8-bit PWM timer.
This function becomes valid when output from PWM0 – PWM2 are
enabled.
This is a general-purpose I/O port.

This is a request input pin of the DTP/external interrupt circuit ch.0
and 1.
Because this input is used as required when the DTP/external
interrupt circuit is performing input operations, and it is necessary
to stop outputs from other functions unless such outputs are made
intentionally.
This is a general-purpose I/O port.
This is an input pin of the DTP/external interrupt circuit ch.2.
Because this input is used as required when the DTP/external
interrupt circuit is performing input operations, and it is necessary
to stop outputs from other functions unless such outputs are made
intentionally.
This is a trigger input pin of the 8/10-bit A/D converter.
Because this input is used as requited when the 8/10-bit A/D
converter is performing input operations, and it is necessary to
stop outputs by other functions unless such outputs are made
intentionally.
This is a general-purpose I/O port.
This function is always valid.
This function becomes valid when output from PWM3 is disabled.
This is a request input of the DTP/external interrupt circuit
ch. 3.
Because this input is used as required when the DTP/external
interrupt circuit is performing input operations, and it is necessary
to stop outputs from other functions unless such output are made
intentionally.
This is an output pin of 8-bit PWM timer.
This function becomes valid when output from PWM3 is enabled.
This is a general-purpose I/O port.
This function becomes valid when serial data output from UART is
disabled.
This is a serial data I/O pin of UART.
This function becomes valid when serial data output from UART is
enabled.
Because this input is used as required when UART is performing
input operations, and it is necessary to stop outputs by other
functions unless such outputs are made intentionally.
