I am working with MCf52235 and using IR7 as an external interrupt .I want to configure it as to generate an interrupt on the falling edge.
As per the Refernce manaual I intialzed it . But I am not able to see the interrupt .
Can some body help with the intailization code.
Try by below settings
MCF_GPIO_PNQPAR = 0
MCF_GPIO_DDRNQ = 0;
MCF_EPORT0_EPPAR = 0
MCF_EPORT1_EPFR = MCF_EPORT_EPPAR_EPPA7_FALLING;
MCF_EPORT0_EPIER = 0
| | MCF_EPORT_EPIER_EPIE7;
MCF_INTC0_IMRL &= ~(0
map the interrupt in vector.s file
