Function Description

IHRC_16M

High speed internal 16MHz RC. XIN/XOUT become to P1.6/P1.4

bi-direction I/O pins.

Low cost RC for external high clock oscillator and XOUT becomes to P1.4

bit-direction I/O pin.

12M X’tal

High speed crystal /resonator (e.g. 12MHz) for external high clock

oscillator.

High_Clk

4M X’tal

Standard crystal /resonator (e.g. 4M) for external high clock oscillator.

Always_On

Watchdog timer is always on enable even in power down and green

mode.

Enable

Enable watchdog timer. Watchdog timer stops in power down mode and

green mode.

Watch_Dog

Disable

Disable Watchdog function.

Fhosc/1

Instruction cycle is oscillator clock.

Notice: In Fosc/1, Noise Filter must be disabled.

Fhosc/2

Instruction cycle is 2 oscillator clocks.

Notice: In Fosc/2, Noise Filter must be disabled.

Fhosc/4

Instruction cycle is 4 oscillator clocks.

Fhosc/8

Instruction cycle is 8 oscillator clocks.

Fcpu

Fhosc/16

Instruction cycle is 16 oscillator clocks.

Reset

Enable External reset pin.

Reset_Pin

P15

Enable P1.5 input only without pull-up resister.

Enable

Enable ROM code Security function.

Security

Disable

Disable ROM code Security function.

Enable

Enable Noise Filter and the Fcpu is Fosc/4~Fosc/16.

Noise_Filter

Disable

Disable Noise Filter and the Fcpu is Fosc/1~Fosc/16.

LVD_L

LVD will reset chip if VDD is below 2.0V

LVD_M

LVD will reset chip if VDD is below 2.0V

Enable LVD24 bit of PFLAG register for 2.4V low voltage indicator.

LVD

LVD_H

LVD will reset chip if VDD is below 2.4V

Enable LVD36 bit of PFLAG register for 3.6V low voltage indicator.

Note:

In high noisy environment, enable “Noise Filter” and set Watch_Dog as “Always_On”

is strongly recommended. Enable “Noise_Filter” will limit the Fcpu = Fosc/4 ~ Fosc/128.

If users define watchdog as “Always_On”, assembler will Enable “Watch_Dog”

automatically.

Fcpu code option is only available for High Clock. Fcpu of slow mode is Fosc/4 (the

Fosc is internal low clock).
