Bit[4:3]  
CPUM[1:0]: CPU operating mode control bits.  
00 = normal.  
01 = sleep (power down) mode.  
10 = green mode.  
11 = reserved.  
Bit 2  
Bit 1  
CLKMD: System high/Low clock mode control bit.  
0 = Normal (dual) mode. System clock is high clock.  
1 = Slow mode. System clock is internal low clock.  
STPHX: External high-speed oscillator control bit.  
0 = External high-speed oscillator free run.  
1 = External high-speed oscillator free run stop. Internal low-speed RC oscillator is still running.  
¾
Example: Stop high-speed oscillator and PLL circuit.  
B0BSET FSTPHX ; To stop external high-speed oscillator only.  
Example: When entering the power down mode (sleep mode), both high-speed external oscillator, PLL circuit  
and internal low-speed oscillator will be stopped.

FCPUM0  
; To stop external high-speed oscillator and internal low-speed  
; oscillator called power down mode (sleep mode).
