Symmetric Key Hardware Accelerator (SKHA)
The value written to the IV/Nonce registers will be replaced with the running initialization vector,
IV, (CBC mode) or running counter (CTR mode) once processing begins.
If any context registers are read prior to the SKSR[DONE] bit being set, an early read error,
SKESR[ERE], will be generated and an interrupt request will be sent to the interrupt controller (if
ERE is not masked).
30.3
At the top level, the SKHA consists of seven functional blocks: The input FIFO, the output FIFO,
transmit FIFO interface, receive FIFO interface, internal bus interface, top control and the SKHA
logic.
