The AES module provides four trigger sources which can be configured to source DMA trigger 2. In order of decreasing interrupt priority, the DMA2 trigger events from the AES are given in Table 28-341. When the DMA2 channel is needed by the AES for block cipher operations, the DMA2 trigger should be unmasked in the IMASK register of DMA_TRIG2 and the DMA should be configured as needed to support the AES operation.
Index (IIDX) | Name | Description |
---|---|---|
0 | AESRDY | Not to be used for normal operation. |
1 | DMA0 | Not to be used for normal operation. |
2 | DMA1 | Not to be used for normal operation. |
3 | DMA2 | DMA2 trigger indication |
The DMA trigger 2 event configuration is managed with the DMA_TRIG2 event management registers. See Section 7.2.5 for guidance on configuring the event registers for DMA triggers.
