ADVANCE PRODUCT INFORMATION - JUL 26, 2011
6.6
The interrupt controller generates the output signal at pin INTN. All interrupt sources except of XORIRQ
can be masked. ISTAT is the interrupt status register. The interrupt is kept active until the
corresponding status register has been read. If all interrupts are masked the software is still able to
recognize interrupts by polling the status register.
The following Table 29 lists all modules which can generate interrupts. The interrupts are explained in
detail in the corresponding chapters.
