DMA trigger during transition into LPM1/LPM2/LPM3/LPM4 may cause the device to reset
The device performs a PUC if the DMA is triggered while the system transitions the power mode from active to LPM1/LPM2/LPM3/LPM4. The susceptible time window at power mode transition is 1 MCLK cycle + 500ns.
Ensure that the DMA is not triggered during active mode to LPM1/LPM2/LPM3/LPM4 transition.
1. Perform a software DMA trigger inside a module interrupt service routine instead of using the modules DMA trigger.
OR
2. Use Active Mode or LPM0 when using DMA.
