Working on MSP432 - Part 6 (Low Power Mode - LPM3. 5)

This article shows the code snippet on how to move MSP432 to LPM3.5 mode. The evaluation board MSP-EXP432P401R Rev2. 0 has been used for testing. 

Following conditions have been met. 

1. Click set to LFXTCLK

2. The GPIO set to output mode and output is set to NULL

3. The procedure defined in section 8.20 of the reference manual has been followed. Snapshot of the procedure below. 

The code snippet from the written code is as below

The evaluation board was used and debugger jumpers have been removed. Only the 3.3v and GND jumpers have been retained.

The minimum current that can be achieved with all the configuration above is 8.192uA.

The MSP432 datasheet shows the below current consumption under the LPM3. 5 mode. There is still some more configuration that need to be done before the consumption from the datasheet to be achieved.
