Name and Function
LPC command, address, and data input/output pins.
Input pin that indicates the start of an LPC cycle or
forced termination of an abnormal LPC cycle.
Input pin that indicates an LPC reset.
The LPC clock input pin.
Input/output pin for LPC serialized host interrupts
(HIRQ1, SMI, HIRQ6, HIRQ9 to HIRQ12).
LPC auxiliary output pins. Functionally, they are general
I/O ports.
A20 gate control signal output pin. Output state
monitoring input is possible.
Input/output pin that requests the start of LCLK
operation when LCLK is stopped.
Input pin that controls LPC module shutdown.
Matrix keyboard input pins. KIN0 to KIN15 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
Wakeup event input pins. These pins allow the same
kind of wakeup as key-wakeup from various sources.

C clock I/O pins. The output type is NMOS open-drain
C data I/O pins. The output type is NMOS open-drain
16-input, 256-key matrix to be configured.
