Other Parts Discussed in Thread: MSP430F6638
Hi,
We are trying to use Supercap as a backup for RTC at VBAT pin. In MSP430F5338, A12 channel (in ADC) is specifically allocated for Monitoring the supercap voltage. What is the voltage source for ADC (A12) while working for VBAT Measurement and what registers need to configure to use A12 channel for battery measurement? (We enabled VBAT Measurement reg in BAKCTL register)
Without connecting Supercap to A12 Externally, Supercap charging not happening.
