Register 19: SHA Length (SHA_LENGTH), offset 0x048
WRITE: Block Length/Remaining Byte Count (bytes) READ: Remaining Byte Count. The value
programmed MUST be a 64-byte multiple if Close Hash is set to 0. This register is also the trigger
to start processing: once this register is written, the core will commence requesting input data via
DMA or IRQ (if programmed length > 0) and start processing. The remaining byte count for the
active operation can be read from this register when the interrupt status register indicates that the
operation is suspended due to a context switch request.
