I am currently using an MSP430FR5720 in my system. What I would like to do is cycle between an ON state and LPM. Say, 100ms ON, 400ms LPM; something similar to that. While the MCU is awake, that is when I will be listening for a signal on a channel. If what is received is what I want, the system will stay awake for a certain amount of time, continuing its normal routines.
Does the MSP430 have this type of "power cycling" functionality? Is this achieved through interrupts? Any information is appreciated.
