5.2 SYSTEM MODE SWITCHING EXAMPLE

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

B0BSET

FCPUM0

; Set CPUM0 = 1.

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

Example: 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.

Example: Switch slow mode to normal mode (The external high-speed oscillator is still running).

B0BCLR

FCLKMD

;To set CLKMD = 0

Example: Switch slow mode to normal mode (The external high-speed oscillator stops).

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.

MOV

A, #27

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

B0MOV

Z, A

@@:

DECMS

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

JMP

;

B0BCLR

FCLKMD

; Change the system back to the normal mode

Example: Switch normal/slow mode to green mode.

B0BSET

FCPUM1

; Set CPUM1 = 1.

Note: If T0 timer wakeup function is disabled in the green mode, only the wakeup pin and reset pin can

wakeup the system backs to the previous operation mode.
