Function
K General-purpose I/O port
This pin serves as the D/A converter output pin.
The pin functions when enabled by the control status register.
— A/D converter power supply pin
— “H” reference power supply pin for the A/D converter
— “L” reference power supply pin for the A/D converter
— A/D converter power pin (GND)
J General-purpose I/O port
This port is enabled when the analog input enable register setting is
“port.”
A/D converter analog input pins
These pins are enabled when the analog input enable register setting
is “analog input.”
— Power pin (GND)
J General-purpose I/O port
This port is enabled when the analog input enable register setting is

J General-purpose I/O port
This port is enabled when the analog input enable register setting is
“port.”
A/D converter analog input pin
This pin is enabled when the analog input enable register setting is
“analog input.”
Comparator input pin
L*2 General-purpose I/O port
This port is always enabled.
External interrupt request input 0
Since this pin serves for interrupt request as required when external
interrupt is enabled, other outputs must be off unless used
intentionally.
L*2 General-purpose I/O port
This port is always enabled.
External interrupt request input 1
