Power usage during sleep mode

CCS/EZ430-RF2500-SEH: Entering SLEEP power mode in CC2500

Part Number: EZ430-RF2500-SEH
Other Parts Discussed in Thread: SIMPLICITI, CC2500

Tool/software: Code Composer Studio

Hello,

I am struggling with the power comsumption optimization in my dev kit ez430. I would like to enter the SLEEP mode in CC2500 as often as possible, because the  IDLE mode is too power-consuming. My question is how can I do this. I found a thread on this matter showing this in simpliciTI but I wonder if there is a way to turn it on in MSP as I did for LPM modes in this microcontroller (__bis_SR_register(LPM3_bits + GIE);). I know that for entering SLEEP mode I should probably change the Cheap Select bit or something like that.

Thank you for your help

    How to enter sleep on CC2500 is described in the CC2500 datasheet. On a low level all you have to do is to strobe SPWD, if you are running some other software on top you have to look into that to see which command that is implemented there.
