If MD[24] is pull down, this pin serves as an external interrupt
request. A active high-state in this pin will make EIER[12] be
set. In this mode, this pin can also serve as an interrupt
request pin for an IDE slot.
If MD[24] is pull high, this pin serves a "resume" request to
wake up the chip from "DOZE" mode.
If MD[24] is pull down, this pin serves as an external interrupt

If MD[24] is pull high, this pin serves a "resume" request to
wake up the chip from "SLEEP" mode.
