Hi,

I'm facing problem in placing CLKGEN domain of 5503 to idle mode. I have put all other domains
idle and able to see the idle status in ISR register except CLKGEN domain. 

I want to set all domains idle to reduce the power consumption to a  
minimum.
  
I do as follows:  
>- Clear all interrupt flags (IFR0 and IFR1).  
>- Enable external interrupt 0. This interrupt gives the wakeup from  
idle.  
>- Enable maskable interrupts.  
>- Set the ICR register ( to 0x003F to enable all idle domains).  
>- Execute the IDLE instruction.  
>- After wakeup by external int 0 the ICR is set to 0x0000.  
>- Execute IDLE instruction again (to set everything active and not  
>idle).  
 
Any hints or suggestions?

Thanks in advance
Sennath

hi,

Are the bits 14 and 13 of the EBSR register taken care
properly?

regards,
Dileepan.
