IRQEN — External Interrupt Request Enable
This read/write bit enables external interrupts. Reset clears the IRQEN bit.
0 =
External interrupt processing disabled. LED/IRQ pin return to
normal LED function
1 =
External interrupt processing enabled. LED/IRQ pin set to IRQ
function
IRQS— External Interrupt Sensitivity
This bit makes the external interrupt inputs level-triggered as well as edge-trig-
gered.
0 =
IRQ negative edge-triggered and low level-triggered.
1 =
IRQ negative edge-triggered only.
