C. Internal Block

Please always take in mind that ICE is different from IC. ICE is the whole set of HE80000 series IC, but

each IC is a subset of ICE. Never use any hardware resource that real IC didn't have, especially RAM and

register. KBIDS and compiler cannot prevent user to use some hardware resource that didn't exist. Please

check the following table and refer the abbreviation in HE80000 user's manual.

Description

111,

FXI,

FXO

B,

O

External fast clock pin.

Connecting to crystal or RC

to generate 32.768 kHz ~

8MHz frequency.

114,

113

SXI,

SXO

I,

O

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：Slow Clock only

01：Illegal

10：Dual Clock

11：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

I 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

I Test Pin

Please bond this pin and add a test point on PCB

for debugging. But for improving ESD, please

connect this pin with zero Ohm resistor to GND.
