Description
Undefined Bits
All bits those are marked as “0” (undefined bits) in system registers should be set “0” to
avoid unpredicted system errors.
PWM1
Set PWM1 (P5.3) pin as output mode.
Interrupt
Do not enable interrupt before initializing RAM.
Non-Used I/O
Non-used I/O ports should be set as output low mode or pull-up at input mode to save
current consumption.
Sleep Mode
Enable on-chip pull-up resisters of port 0 and port 1 to avoid unpredicted wakeup.
Stack Buffer
Be careful of function call and interrupt service routine operation. Don’t let stack buffer
overflow or underflow.
System Initial
1. Write 0x7F into STKP register to initial stack pointer and disable global interrupt
2. Clear all RAM.
3. Initialize all system register even unused registers.
Noisy Immunity
1. Enable OSG and High_Clk / 2 code option together
2. Enable the watchdog option to protect system crash.
3. Non-used I/O ports should be set as output low mode
4. Constantly refresh important system registers and variables in RAM to avoid system
crash by a high electrical fast transient noise.
5. Enable the LVD option to improve the power on reset or brown-out reset performance
