Hi expert,
My customer wants to configure CMPSS Comparator into latch mode.
Because they want to make CTRIPOUTH or CTRIPOUTL connecting to an external IPM module, the overcurrent is just in a flash, but the output signal of the comparator is not expected to disappear.
I did not find the function, could you kindly tell me which one can achieve this function. customer is using driverlib.

Hi Emma,
You can configure this using the COMPCTL.CTRIPOUTLSEL and COMPCTL.CTRIPOUTHSEL registers. The latch option is 3.
Frank,
If customer wants to use driverlib, does it OK to do below:
add new value 'CMPSS_TRIP_LATCH' in function CMPSS_configOutputsHigh(), do we need to make other changes?
or could you kindly give me a reference code to achieve this function?

Emma,
Yes that is right. However if the output xbar trip is what you need, then use the corresponding 'CMPSS_TRIPOUT_LATCH' macro instead.
