GPIO interrupt

[prakashpatel]

Hi,

I am trying to setup external interrupt on my target hw. I successfully configured PORTE pin28 interrupt. However when I tried to do the same on PORTA same pin number. MCU is reseting. This specifically happens when I try to set a value in PORTA->DFER .

Any help is appreciated.

Thanks

Hi

Do you power up PORTA (enable clocks to it) before writing to its registers?
