MSP430FR5969: Please clarify below points

Hello Pradeep,

1. If you are referencing reading a battery voltage, this can be done with the ADC12.  See the code example below which takes a sample on A1 and waits in low power mode 0 until the conversion is complete.  

ADC12 example: https://dev.ti.com/tirex/explore/node?node=AM6OnzaAOO6rktD8QJ1WwQ__IOGqZri__LATEST&search=msp430fr5969 

All register based example code: https://dev.ti.com/tirex/explore/node?node=AF2K1gpwMosUXm76mIQpDQ__IOGqZri__LATEST&search=msp430fr5969    

2. The device has 64kB of FRAM that can be used for program code and data. The device also has 2kB of SRAM.

3. See section 1.4.2 of the users guide below which discusses entering and exiting low power modes.
