19.13 Module Configuration
32072G–11/2011
The following table defines the valid settings for the DEST_PER and SRC_PER fields in the
CFGxH register. The direction is specified as observed from the DMACA. So for instance, AES -
RX means this hardware handshaking interface is connected to the input of the AES modulel
