External fast clock pin.
Connecting to crystal or RC
to generate 32.768 kHz ~
8MHz frequency.

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.

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.
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

：
Enable Watch Dog Timer
Please bond this pin and add a test point on PCB for
debugging. Leave this pin floating is OK.
Mask options

Output must be “1” before reading whenever use them
as input (No tri-state structure).
Mask options
：
MO_DPP[7..0]=1 ~ Push-pull.
=0 ~ Open-drain.
Output must be “1” before reading whenever use them
as input (No tri-state structure).
Mask options
