Input/
Output
LPC auxiliary output pins. Functionally,
they are general I/O ports.
GA20 94 130 Input/
Output
A20 gate control signal output pin.
Output state monitoring input is
possible.
CLKRUN 95 131 Input/
Output
Input/output pin that requests the start
of LCLK operation when LCLK is
stopped.
Host

are used as key-scan inputs, and
P10 to P17 and P20 to P27 are used as
key-scan outputs. This allows a
maximum 16-output × 16-input, 256-key
matrix to be configured.

Input A/D conversion input pins, but since
they are also used as digital
input/output pins, accuracy will fall.
