In the Family Guide, the following is stated:
"REFMSTR = 1
This mode is implemented in all devices with ADC10_A. Also all ADC12_A devices except for
MSP430F5438 and MSP430F5438A support this mode."
So does this mean the reference module register has no affect on the Msp430f5438a? The part specific data sheet links to the REF module documentation, so I'm a bit confused.
In this case, how do you ensure the temp sensor is powered?
