MSP430FR5989: Register where DAC reference voltage can appear from ESI

Part Number: MSP430FR5989

Hi TI team,

My costumer wanted to know if it's able to see a register where DAC reference voltage can appear in order to quantify the voltage and see how much is left for the disk to rotate or not. I'm using flow metter application, here is a pic of the needed:

In the dataseeht I've seen some DAC register but I can't affirm if with these register my customer can do it or no.

Best regards

Samuel
