GPIO interrupt

prakashpatel — Mon, 26 May 2014 18:58:35 GMT

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

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

Thank you for your reply.

good question. I am enabling all clock. see following instruction.

SIM_SCGC5 |= 0x3E00UL
