Matrix keyboard input pins. All pins have a wake-
up function. Normally, KIN15 to KIN0 function as
key scan inputs, and P17 to P10 and P27 to P20
function as key scan outputs. Thus, at a
maximum of 16 outputs x 16 inputs, 256-key
matrix can be configured.

Output Analog output pins
AVCC 76 Input Analog power supply pins for the A/D converter
and D/A converter. When the A/D converter and
D/A converter are not used, these pins should be
connected to the system power supply (+3.3 V).
AVref 77 Input Reference voltage input pin for the A/D converter
and D/A converter. When the A/D converter and
D/A converter are not used, this pin should be
connected to the system power supply (+3.3 V).
