Name and Function
Synchronous clock
input/output pins for the
keyboard buffer control unit
Data input/output pins for
the keyboard buffer control
unit
Input pins for matrix
keyboard. Normally, KIN15
to KIN0 function as key
scan inputs, and P17 to
P10 and P27 to P20
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.
These pins have interrupt
request flags.
