。
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
。
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

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.
