The AES subsystem interfaces with the DMA module as shown in Table 31-1. Input/output context and data ports from the AES directly feed to the DMA trigger source. Two interrupt registers are included, AES_GLB_INT_FLG and AES_GLB_INT_CLR. AES_GLB_INT_FLG, that provide the status of the secure interrupt generated by the AES while AES_GLB_INT_CLR clears the flag. AES only allows word access. Non-word access (not 32-bit access) generates an interrupt and is aggregated in SYS_ERR.
