Part Number: MSP430FR5869

Hi Champ,

I would like to confirm possibility of PIN function change. C0 ->A0 after Active mode.

I have describe this step.

1: Pin1 : （P1.0/TA0.1/DMAE0/RTCCLK/A0/C0/VREF-/VeREF-） function assigned "C0" comparator mode and waiting interrupt

2: when this icomparator value change, this system move to active mode. Then, this PIN 1 function change to A0 as ADC from C0.

I think this solution is possible. but, I would like to make sure it.

Could you tell us this possibility ?

Yes, this is possible. Both PxSEL bits should already be set from your C0 usage and if you now configure the ADC and it's input multiplexer to use A0, you're done.

Hi Champs,

Thanks.

How long does this takes a time when tha comp_E detect thresh hold voltage and change to active mode and ADC mode and converting 1st ADC sample ?
