Name and Function
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.
Wake-up event input pins. Same wake up as key
wake up can be performed with various sources.
Analog input pins
External trigger input pin to start A/D conversion
Analog output pins
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).
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).
Ground pins for the A/D converter and D/A
converter. These pins should be connected to the
system power supply (0 V).
