Interrupt Source
IRQE can be read anytime and written once in normal modes. In
special modes, IRQE can be read anytime and written anytime,
except the first write is ignored.
The IRQ pin has an internal pull-up.
IRQEN can be read and written anytime in all modes.
0 = IRQ configured for low-level recognition.
1 = IRQ configured to respond only to falling edges (on pin PE1/
0 = External IRQ pin is disconnected from interrupt logic.
1 = External IRQ pin is connected to interrupt logic.
