Function

Description

FXI,

FXO

External fast clock pin.

Connecting to crystal

or RC to generate

32.768 kHz ~ 8MHz

system clock.

SXI,

SXO

External slow clock

pin. Connecting with

32.768 Hz OSC to

generate

the

stable

frequency for Slow

Clock Mode and Timer

clock source.

Mask Option settings：

MO_FCK/SCKN=00：Slow Clock only

01：Illegal

10：Dual Clock

11：Fast Clock only

MO_FOSCE=0：Internal fast oscillation

1： External fast oscillation

MO_FXTAL=0：R,C oscillation for Fast Clock

1：Crystal oscillation for Fast Clock

MO_SXTAL=0：R,C oscillation for 32.768K Clock

1 ： Crystal oscillation for 32.768K

Clock。

Program the value of OP1and OP2 to change the

operating modes (Normal, Slow, Idle and Sleep).

In Dual Clock mode , the system runs in Fast Clock,

only the LCD and timer I use the 32.768K clock

source。

RSTP_N

I System reset signal

Pull this pin to low level to reset the system. Besides,

select the Mask Option (MQ_PORE=1) to enable the

HE83R126 internal Power-on Reset function.

In addition, the MO_WDTE is used for Watch

Timer setting：

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.

PRTD[7:0]

Port D bi-directional

I/O pin ， (8 pins).

PRTD[7:2] is also a

Wake-up

and

PRTD[7:6] is used for

interrupt input pin.

Mask Option MO_DPP[7:0] to preset the output type：

MO_DPP= 1: Push-pull output;

= 0: Open-drain output

When assigned the port to input pin, send a ’1’ and read

the result to get the input value
