Other Parts Discussed in Thread: MSP430F2618
my MSP430FR5964 runs at 2.8 V.
Now I am looking for a way to trigger an interrupt if the supply voltage VCC falls below 2.5 or 2.0 V.
With the MSP430F2618 you had the SVS module and could set the desired voltage.
Unfortunately I cannot set a threshold voltage for the SVS module on the MSP430FR5964.
Then I read that it is possible to use the COMP_E module for this.
As input voltage Vcc and as reference, a voltage from the internal reference module, e.g. 2.0V.
I don't understand here how the reference voltage is kept at 2V while Vcc drops below 2V ?
Or is there a simpler solution to monitor the supply voltage?
I am grateful for any help.
