Problem:
Hi!
I have single configuration: MSP connected to CC with SPI, where CC is in master mode and MSP in slave. In normal life they communicate within 1 to 10 seconds. Now MSP once per 3s wants to transmit data to CC, but also I want MSP to save as much energy as possible.
I wonder when and how can I go LPM with MSP, i.e. can I go LPM4 and still have SPI open with interrupt registered? Or should I close SPI every time when I want go LPM and wake up processor with GPIO interrupt?
How can I (or how should I?) combine SPI with LPM?
