3.3.1.3
Special events in the FALC
programmable characteristics (open drain or push-pull, defined by register IPC), which
requests the CPU to read status information from the FALC
the FALC
Since only one INT request output is provided, the cause of an interrupt must be
determined by the CPU by reading the FALC
The interrupt on pin INT and the interrupt status bits are reset by reading the interrupt
status registers. Register ISR(5:0) are of type “clear on read“.
The structure of the interrupt status registers is shown in
Figure 10
Each interrupt indication of registers ISR(5:0) can be selectively masked by setting the
corresponding bit in the corresponding mask registers IMR(5:0). If the interrupt status
bits are masked they neither generate an interrupt at INT nor are they visible in ISR(5:0).
GIS, the non-maskable Global Interrupt Status Register, serves as pointer to pending
interrupts. After the FALC
should first read the Global Interrupt Status register GIS to identify the requesting
