Go. Indicates that all data has been loaded into the input FIFOand the module should
complete all processing. This bit is self clearing.
0 Do not complete all processing.
1 Finish all processing.
Clear IRQ. Clears errors in the MDISR register and deasserts any interrupt requests from
the MDHA module. This bit is self clearing.
0 Do not clear interrupts & errors.
1 Clear interrupts & errors.
Re-initialize. Re-initializes memory and clears all registers except the MDESM and MDCR.
0 No re-initialization
1 Re-initialize the MDHA module
Software reset. Resets all registers and re-initialize memory of the MDHA. Functionally
equivalent to hardware reset. This bit is self clearing.
0 No reset
1 Software reset
Reserved, should be cleared.
Input FIFO level. Read-only. The current number of longwords that are in the Input FIFO.
IFL will range from 0–16 longwords (0x00-0x10).
