Hi,
As i have zerocross detection circuit made up of H11AA1 IC and tried to give that zc signal to one of our external interrupt pin of MSF430FR2633 capacitive touch development board (Supply 3.3V for controller and secondary side of H11AA1 are from same source) i was unable to receive Ext interrupt so when cross checked that issue i found that the ZC pulse Amplitude was getting dropped from 3.3V to 2V as soon as i connect that ZC signal to INTERRUPT PIN ??????????
need help to find out this issue
