Port [A/B/C/D/E] Interrupt Enable by Input Rising Edge or Input Level High
IR_EN[n] used to enable the interrupt for each of the corresponding input
GPIO_PIN[n]. Set bit to 1 also enable the pin wakeup function
When set the IR_EB[n] bit to 1:
If the interrupt is level trigger, the input PIN[n] state at level “high” will generate the
interrupt.
If the interrupt is edge trigger, the input PIN[n] state change from “low-to-high” will
generate the interrupt.
1 = Enable the PIN[n] level-high or low-to-high interrupt
0 = Disable the PIN[n] level-high or low-to-high interrupt
Port [A/B/C/D/E] Interrupt Enable by Input Falling Edge or Input Level Low
IF_EN[n] used to enable the interrupt for each of the corresponding input
GPIO_PIN[n]. Set bit to 1 also enable the pin wakeup function
When set the IF_EB[n] bit to 1:
If the interrupt is level trigger, the input PIN[n] state at level “low” will generate the
interrupt.
If the interrupt is edge trigger, the input PIN[n] state change from “high-to-low” will
generate the interrupt.
1 = Enable the PIN[n] state low-level or high-to-low change interrupt
0 = Disable the PIN[n] state low-level or high-to-low change interrupt
