AES Polling Mode
Main Sequence: AES Polling Mode – Figure 7-102 shows AES polling mode. The registers used in AES polling mode follow:
AES Interrupt Mode
The application can use software interrupts to control the flow of Context In, Context Out, Data In, and Data Out requests. To enable these interrupts:
If the application uses interrupt mode, an interrupt is generated for each block of processed data. To support larger data flow, AES DMA mode should be used and the bits in the S_IRQENABLE register should be cleared.
AES DMA Mode
When AES DMA mode is enabled, the S_IRQENABLE register should be cleared. To enable the DMA to transfer data, follow these steps:
The input buffer registers, S_DATA_IN_n, are now loaded.
