SYSTEM MODE SWITCHING

Switch normal/slow mode to power down (sleep) mode.

CPUM0 = 1

B0BSET

FCPUM0

; set the system into power down mode.

During the sleep, only the wakeup pin and reset can wakeup the system back to the normal mode.

Switch normal mode to slow mode.

B0BSET

FCLKMD

;To set CLKMD = 1, Change the system into slow mode

B0BSET

FSTPHX

;To stop external high-speed oscillator for power saving.

Switch slow mode to normal mode

If external high clock stop and program want to switch back normal mode. It is necessary to delay at least 10mS for

external clock stable.

B0BCLR

FSTPHX

; Turn on the external high-speed oscillator.

B0MOV

Z, #27

; If VDD = 5V, internal RC=32KHz (typical) will delay

@@:

DECMS

; 0.125ms X 81 = 10.125ms for external clock stable

JMP

;

B0BCLR

FCLKMD

; Change the system back to the normal mode
