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 active pull-up. See
IRQEN can be read and written anytime in all modes.
The delay time of about 4096 cycles is based on the X clock rate
chosen.
DLY can be read anytime and written once in normal modes. In
special modes, DLY can be read and written anytime.
