A
This is a high-speed crystal oscillator pin.
B
This is a low-speed crystal oscillator pin.
C
This is an input pin for selecting operation modes.

.
This is an external reset request signal input pin.
This is a hardware stand-by input pin.
This is a general-purpose I/O port.
This function can be set by the port 0 input pull-up resistor setup
register (RDR0) for input. For output, however, this function is
invalid.
This is a request input pin of the DTP/external interrupt circuit ch.0
to ch.6.
This is a general-purpose I/O port.
This function can be set by the port 0 input pull-up resistor setup
register (RDR0) for input. For output, however, this function is
invalid.
This is a general-purpose I/O port.
This function can be set by the port 1 input pull-up resistor setup
register (RDR1) for input. For output, however, this function is
invalid.
This is an I/O pin for wake-up interrupts.
This is a general-purpose I/O port.

This is a trigger input pin for input capture (ICU) 0 and 1.
Since this input is used as required for input capture 0 and 1 (ICU)
ch.0, ch.01, ch.10 and ch.11 input operation, output by other
functions must be suspended except for intentional operation.
This is a general-purpose I/O port.
This port can be used as count clock A input for 8/16-bit up/down
counter/timer 0.
This is a general-purpose I/O port.
This port can be used as count clock B input for 8/16-bit up/down
counter/timer 0.
