MSP430F6779A: Are there any specification which modules operate in LPM3?

TinK

Part Number: MSP430F6779A

Tool/software:

we have an intermittent process that wakes up every 1 second.
(Wake up every 1 second by RTC interrupt then go to sleep periodically)

Does the auxiliary power module operate only after wake up? (or always operate LPM3)

Are there any specification which modules operate in LPM3?

Hi Tink,

Any peripheral you have set to use ACLK will be running on ACLK and will be on during LPM3. If you want the lowest power then you can run at LPM3.5 and have your RTC trigger the device to wake.

Hi Luke,

and also Any peripheral you have set to use VLO clock (auxiliary power module) right?

Only if VLO clock is sourced to ACLK. If VLO is sourced to SMCLK, SMCLK will still turn off so peripherals that use SMCLK will not be clocked.
