The channel section at Security Engine gives you access to execution unit. 4 Channels are available for you to do multiple cryptographic processing at one time. The channel section is consisted of Channel Configuration Register (CCR), Channel Status Register (CSR), Current Descriptor Pointer Register (CDPR), Fetch FIFO Enqueue Register (FFER), Descriptor Buffer (DB), Scatter Link Tables (SLT), and Gather Link Tables (GLT).
