Special events in the FALC
programmable characteristics (open drain, push-pull; IPC register), which requests the
CPU to read status information from the FALC
LH.
Since only one INT request output is provided, the cause of an interrupt must be
determined by the CPU by reading the FALC’s interrupt status registers (GIS, ISR0...3,
ISR5) that means the interrupt at pin INT and the interrupt status bits are reset by reading
the interrupt status registers. Register ISR0...3,5 are from type “Clear on Read“.
The structure of the interrupt status registers is shown in
