This is a general-purpose I/O port.
This function can be set by the port 4 input pull-up resistor setup
register (RDR4) for input. For output, however, this function is
invalid.
This is a data output pin for extended I/O serial interface 0.
This function becomes valid when serial data output from SOT1 is
enabled.
This is a general-purpose I/O port.
This function can be set by the port 4 input pull-up resistor setup
register (RDR4) for input. For output, however, this function is
invalid.
This is a serial clock I/O pin for extended I/O serial interface 0.
This function becomes valid when serial clock output from SCK1 is
enabled.
This is a general-purpose I/O port.
This is a data input pin for extended I/O serial interface 1.
Since this input is used as required for serial data input operation,
output by other functions must be suspended except for intentional
operation.
This port can be used as count clock A input for 8/16-bit up/down
counter/timer 1.
This is a general-purpose I/O port.
This is a data output pin for extended I/O serial interface 1.
This function becomes valid when serial data output from SOT2 is
enabled.
This port can be used as count clock B input for 8/16-bit up/down
counter/timer 1.
This is a general-purpose I/O port.
This is a serial clock I/O pin for extended I/O serial interface 1.
This function becomes valid when serial clock output from serial
SCK2 is enabled.
This port can be used as control clock Z input for 8/16-bit up/down
counter/timer 1.
This is a general-purpose I/O port.

These are analog signal output pins for 8-bit D/A converter ch.0
and ch.1.
This is a general-purpose I/O port.
The input function become valid when the analog input enable
register (ADER) is set to select a port.
These are analog input pins of the 8/10-bit A/D converter.
This function is valid when the analog input enable register
(ADER) is enabled.
