Function
AC zero-cross
detection
input pins
Key interrupt
input pins
Description
AC zero-cross detection input pin.
AC zero-cross detection output “H” when input level is
mid-level and “L” otherwise.
ACZ input signal is connected to P20 input and IRQ0
interrupt circuit or P21 input and IRQ1 interrupt circuit.
When not used for AC zero-cross detection, these can
be used as normal input pins.
Input pins for interrupt based on OR result of pin
inputs.
These can be set to key input pins by 1-bit with the
key interrupt control register (KEYT3_1IMD,
KEYT3_2IMD) and by 2-bit with the key interrupt con-
trol register (KEYT3_1IMD).
When not used for KEY input, these pins can be used
as normal I/O pins.
LED drive pins
Large current output pins.
When not used for LED output, these pins can be
used as normal I/O pins.
Write enable pins
[Active low]
Read enable pins
[Active low
Chip select pins
[Active low]
Data acknowl-
edge pins [Active
low]
Memory control signal used when the memory area is
expanded to the external of this LSI.
NWE is the strobe signal output for the write operation
of the external memory and NRE is the strobe signal
output for the read operation of the external memory
NCS is the chip selection signal outputs the external
memory at the access.
NDK is the acknowledge signal that indicates close of
access to the external memory.
Address pin
A0-A19 is the address signal to the external memory.
D0-D7 is the data I/O signal to the external memory.
