The SPI module contains three event publishers and no event subscribers. One event publisher (CPU_INT) manages SPI interrupt requests (IRQs) to the CPU subsystem through a static event route. The second and third event publishers (DMA_TRIG_RX, DMA_TRIG_TX) are used to setup the trigger signaling for the DMA through DMA event route.
The SPI events are summarized in Table 17-2.
Event | Type | Source | Destination | Route | Configuration | Functionality |
---|---|---|---|---|---|---|
CPU interrupt | Publisher | SPI | CPU Subsystem | Static route | CPU_INT registers | Fixed interrupt route from SPI to CPU |
DMA trigger | Publisher | SPI | DMA | DMA event route | DMA_TRIG_RX registers | Fixed interrupt route from SPI RX to DMA |
DMA trigger | Publisher | SPI | DMA | DMA event route | DMA_TRIG_TX registers | Fixed interrupt route from SPI TX to DMA |
