µDMA channel numbers four and five are assigned to AES Channels A and B. Each channel has an interface consisting of µDMA request and µDMA done signals. Configure µDMA channels to specify the total transfers. For multi-block encryption, specify the total transfers required for all the blocks. The µDMA request signal is generated by AES to alert µDMA for data transfer. The µDMA done signal from the µDMA indicates the completion of all data transfers.
