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 ×
16-input, 256-key matrix to be configured.
Wakeup event input pins. These pins allow
the same kind of wakeup as key-wakeup
from various sources.
Analog input pins.
Pin for input of an external trigger to start A/D
conversion.
The analog power supply pin for the A/D
converter.
When the A/D is not used, this pin should be
connected to the system power supply (+3
V).
The reference power supply pin for the A/D
converter and.
When the A/D is not used, this pin should be
connected to the system power supply (+3
V).
The ground pin for the A/D converter. This
pin should be connected to the system power
supply
(0 V).
