    9.3 Interrupt Control and Priority Registers
    IRQE — IRQ Select Edge Sensitive Only
    0 = IRQ configured for low-level recognition.
    1 = IRQ configured to respond only to falling edges (on pin PE1/IRQ).
    IRQE can be read anytime and written once in normal modes. In special modes, IRQE can be read any-
    time and written anytime, except the first write is ignored.
    IRQEN — External IRQ Enable
    The IRQ pin has an internal pull-up.
    0 = External IRQ pin disconnected from interrupt logic
    1 = External IRQ pin connected to interrupt logic
    IRQEN can be read and written anytime in all modes.
    DLY — Enable Oscillator Start-Up Delay on Exit from STOP
    The delay time of about 4096 cycles is based on the E clock rate.
    0 = No stabilization delay imposed on exit from STOP mode. A stable external oscillator must be
    supplied.
    1 = Stabilization delay is imposed before processing resumes after STOP.
    DLY can be read anytime and written once in normal modes. In special modes, DLY can be read and
    written anytime.
