Pin #

Pin name I/O

Function

Description

FXI,

FXO

External fast clock pin.

Connecting to crystal or RC

to generate 32.768 kHz ~

8MHz frequency.

SXI,

SXO

External slow clock pin.

Connecting with 32768 Hz

crystal or resistor as slow

clock and providing clock

source for LCD display,

TIMER1, Time-Base and

other internal blocks.

Mask option setting

MO_FCK/SCKN= 00 œ Slow Clock only

01 œ Illegal

10 œ Dual Clock

11 œ Fast Clock only

MO_FOSCE = 0 Internal fast osc.

= 1 External fast osc.

MO_FXTAL= 0 RC osc. for fast clock

= 1 X’tal osc. for fast clock

MO_SXTAL= 0 RC for 32768 Hz clock

= 1 X’tal for 32768 Hz clock

Use OP1 and OP2 to switch among different operation

mode (NORMAL, SLOW, IDEL and SLEEP). In Dual

Clock mode, the main system clock is still the Fast Clock.

The 32768 Hz clock is for LCD and Timer 1 only.

RSTP_N

System Reset.

Level trigger, active low. Except for using this pin, using

mask option (MO_PORE=1) could enable IC build-in

power-on reset circuit.

Besides, MO_WDTE can set Watch Dog Timer

MO_WDTE=0 Disable Watch Dog Timer

=1 Enable Watch Dog Timer

TSTP_P

Test Pin

Please bond this pin and add a test point on PCB for

debugging. Leave this pin floating is OK.

LV3< 9 Volts.

Please refer the application circuit.

PWMP

The PWM positive output

can drive speaker or buzzer

directly.

Set the bit2 of VOC register as one to turn on PWM.
