8.2
Some events in the INCA-D are indicated by means of a single interrupt output. Thus the
interrupt request nodes irq(3), irq(4), irq(13) and irq(14) represent combined interrupt
requests.
Since only one interrupt line is provided, the cause of an interrupt can be determined by
reading the corresponding interrupt node status registers which belongs to the interrupt
node. These nodes are described in the following sub-chapters.
The name of status register referring to node irq(x) is IRQxx_STA.
Note: After reading the interrupt request or interrupt status register, they will be cleared.
8.2.1
The interrupt 3 comprises all interrupts that are related to the USB device itself.
The USB device interrupt request register DIRR contains the device specific interrupt
flags of the USB module. These flags are set after the occurrence of special events. If a
request flag has been set, it is automatically cleared after a read operation of the DIRR
register.
The interrupts contained in the DIRR register can individually be masked in the DIER
register. For further details refer to Chapter 22.
The structure is shown in figure 8-1.
