Function expect a port function

Power source

(Note 1)

•Apply voltage of 2.2 to 5.5 V to Vcc, and 0 V to Vss.

VREF

CNVss

RESET

XIN

CNVss

•Chip operating mode control pin, which is always connected to Vss.

Reset input

Clock input

•Reset input pin for active “L”

•Input and output pins for main clock generating circuit.

•Connect a ceramic resonator or quartz crystal oscillator between the XIN and XOUT pins.

For using RC oscillator, short between the XIN and XOUT pins, and connect the capacitor and resistor.

•If an external clock is used, connect the clock source to the XIN pin and leave the XOUT pin open.

•

XOUT

Clock output

•

When the ring oscillator is selected as the main clock, connect XIN pin to VCC and leave XOUT open.

• Key-input

P01(LED01)/CMP0

P02(LED02)/CMP1

P03(LED03)/TXOUT

P04(LED04)/RxD2

• Capture function pin

• Compare function pin

•I/O direction register allows each pin to be individually pro-

grammed as either input or output.

•CMOS compatible input level

•CMOS 3-state output structure

•Whether a built-in pull-up resistor is to be used or not can be

determined by program.

I/O port P1

• Serial I/O1 function pin

• Capture function pin

• Serial I/O1 function pin

•I/O direction register allows each pin to be individually pro-

grammed as either input or output.

P11/TxD1

•CMOS compatible input level

P12/SCLK1

P13/SRDY1

P14/CNTR0

•CMOS 3-state output structure

•CMOS/TTL level can be switched for P10, P12 and P13

•8-bit I/O port having almost the same function as P0

•CMOS compatible input level

P31(LED11)/CMP2 (Note 3)

P32(LED12)/CMP3

P33(LED13)/INT1

• Capture function pin

• Compare function pin

•I/O direction register allows each pin to be individually pro-

grammed as either input or output.

•CMOS compatible input level (CMOS/TTL level can be

switched for P36 and P37).

• Interrupt input pin

P34(LED14)

•CMOS 3-state output structure

P35(LED15)

•Whether a built-in pull-up resistor is to be used or not can be

determined by program.

P36(LED16)/INT1

P37(LED17)/INT0

•

High drive capacity for LED drive port can be selected by program.

Notes 1: VCC = 2.4 to 5.5 V for the extended operating temperature version and the extended operating temperature 125 °C version.

2: P26/AN6 and P27/AN7 do not exist for the 32-pin version, so that Port P2 is a 6-bit I/O port.

3: P35 and P36/INT1 do not exist for the 32-pin version, so that Port P3 is a 6-bit I/O port.
