‘End Of Interrupt’ Locations
These locations are written to after the appropriate interrupt has been serviced. The write is per-
formed to clear the interrupt status bit, so that other interrupts can be serviced. Any value may be writ-
ten to these locations.

5.13.2 MCEOI Media Changed End of Interrupt
ADDRESS: 0x8000.0640
A write to this location will clear the interrupt generated by a falling edge of the nMEDCHG input pin.
