Remarks
50~52 P2-0~P2-2 I/O port 2
I/O port 2
53 P2-3/PSC /Prescaler
/PSC output
The input and output of these 4 bit I/O
ports can be programmed in 1 bit units.
The P2-3 pin is also used as a PLL
prescaler PSC signal output pin. A PLL
can be configured using an external
prescaler. In such a case, set the pin to
I/O port output.

P3-0
P3-1/SI
42~45 P3-2/SO
P3-3/SCK
4 bit I/O ports, allowing input and output
to be programmed in 1 bit units. The I/O
ports are N-ch open drain.
Up to 3.6 V can be input. Even at low
voltage, N-ch high output current (2 mA
typ.) can be obtained.
These pins also function as serial
interface circuit (SIO) input/output pins.
I/O port 3
/Serial data input
There are two types of serial interface
circuit: SIO1 allows 4 or 8 bit
input/output and SIO2 allows 26 bit
serial data input. SIO1 inputs data of SI
pin serially with the edge of the clock of
SCK pin, and outputs it to SO pin.
/Serial data output
Internal (SCK = 37.5 kHz) or external,
or rising/falling shift can be selected as
the clock (SCK) for serial operation.
The SO pin can be switched to serial
input (SI), facilitating LSI control and
communication between controllers.
/Serial clock I/O
Setting “1” in the SIO2 bit sets the SCK
pin to the SIO2 clock input and the
SI/SO pin to SIO2 data input. A
synchronization circuit is built-in for
SIO2.
When SIO interrupts are enabled, an
interrupt is generated after SIO
execution or by SIO2 operating clock
input and the program jumps to address
4.
All SIO inputs use built-in Schmitt
circuits.
SIO and all controls are programmable.

P4-0/BUZR
I/O port 4
/Buzzer output
29~31 P4-1~P4-3 I/O port 4
4-bit I/O ports, allowing input and output
to be programmed in 1-bit units.
The P4-0 pin is also used for buzzer
output.
The buzzer output can select 8 kinds of
0.625 to 3 kHz frequencies with 4
modes: continuous output, single-shot
output, 10 Hz intermittent output, and
10 Hz intermittent 1 Hz interval output.
SIO, buzzer, and all associated controls
can be programmed.
