15.0 HALT Mode  
17.0 IDLE Mode  
The HALT mode is a power saving feature that almost completely  
shuts down the device for current conservation. The device is  
placed into HALT mode by setting the HALT enable bit (EHALT)  
of the HALT register through software using only the “LD M, #”  
instruction. EHALT is a write only bit and is automatically cleared  
upon exiting HALT. When entering HALT, the internal oscillator  
and all the on-chip systems including the LBD and the BOR  
circuits are shut down.  
In addition to the HALT mode power saving feature, the device  
also supports an IDLE mode operation. The device is placed into  
IDLE mode by setting the IDLE enable bit (EIDLE) of the HALT  
register through software using only the “LD M, #” instruction.  
EIDLE is a write only bit and is automatically cleared upon exiting  
IDLE. The IDLE mode operation is similar to HALT except the  
internal oscillator, the Watchdog, and the Timer 0 remain active  
while the other on-chip systems including the LBD and the BOR  
circuits are shut down.  
The device can exit HALT mode only by the MIW circuit. There-  
fore, prior to entering HALT mode, software must configure the  
MIW circuit accordingly. (See Section 9) After a wakeup from  
HALT, a 1ms start-up delay is initiated to allow the internal  
oscillator to stabilize before normal execution resumes. Immedi-  
ately after exiting HALT, software must clear the Power Mode  
Clear (PMC) register by only using the “LD M, #” instruction. (See  
Figure 36)  
The device automatically wakes from IDLE mode by the Timer 0  
overflow every 8192 cycles (see Section 6). Before entering IDLE  
mode, software must clear the WKEN register to disable the MIW  
block. OnceawakefromIDLEmodeistriggered, thecorewillbegin  
normal operation by the next clock cycle. Immediately after exiting  
IDLE mode, software must clear the Power Mode Clear (PMC)  
register by using only the "LD M, #" instruction. (See Figure 37)
