Interrupt Requests | ||||
Module Instance | Source Signal Name | IRQ_CROSSBAR | Default Mapping | Description |
RTC | RTC_SS_IRQ_ALARM | IRQ_CROSSBAR_217 | - | Alarm interrupt going to device IRQ_CROSSBAR. |
No DMA Requests |
The Default Mapping column in Table 23-4, RTC Hardware Requests shows the default mapping of module IRQ source
signals. These IRQ source signals can also be mapped to other inputs of each
device Interrupt controller through the IRQ_CROSSBAR module.
For more information about the IRQ_CROSSBAR
module, see IRQ_CROSSBAR Module Functional Description, in Control
Module.
For more information about the
device interrupt controllers, see Interrupt Controllers.
