Name and Function
Matrix keyboard input pins. All pins have a wake-
up function. Normally, KIN0 to KIN15 function as
key scan inputs, and P10 to P17 and P20 to P27
function as key scan outputs. Thus, composed
with a maximum of 16 outputs x 16 inputs, a 256-
key matrix can be configured.
Wake-up event input pins. Same wake up as key
wake up can be performed with various sources.
