5.3.5 Interrupt Signals
The ABM-3G asserts its interrupt signals MPINT and MPINTD if non-masked interrupt
events are pending in the respective interrupt status registers. Interrupt signals are
deasserted in case all events are cleared by writing â1â to pending interrupt bits (e.g. write
0xFFFFH to the respective Interrupt Status Register). This allows edge sensitive interrupt
implementations.
Interrupt signals are of type âOpen Drainâ to allow wired-or implementations sharing one
interrupt signal with other devices.
