Note – bit definitions below not symmetric Decap/Encap:
Bit 3: Decapsulator Error Mode (DEM) When set to 1, errored frames are forwarded. Normally they are
discarded. This bit function was located in DMCR bit 0 in device revision A1 (GL.IDR.REVn=000).
Bit 2: Decapsulator State Machine Reset (DSMRE) If this bit is set and DFSRWPC transitions, The
Decapsulator State Machine will be reset.
Bit 1: Decapsulator FIFO Pointer reset Enable (DFPRE) - Setting this bit to a 1 will enable the FIFO to be reset.
The FIFO Read and Write pointer will be reset if DFSRWPC transitions and this bit is set.
Bit 0: Decapsulator FIFO and State Read, Write, and PMU Control (DFSRWPC)- A 0 to 1 transition enables the
FIFO Read and Write Addresses, Status Registers to be read by the processor. The user must wait 4 system
clocks before the reads can be done. This bit is used to control resetting of the FIFO Read and Write Pointers and
the Decapsulator State Machine. This bit is also used as a PMU update for all decapsulator latched counters.
