HCSPASS:
The HCSPASS bit controls the dropping of cells based on the detection of a
HCS error. When HCSPASS is logic 0, cells containing a HCS error are
dropped. When HCSPASS is logic 1, cells are passed to the FIFO interface
regardless of errors detected in the HCS. Additionally, the HCS verification
finite state machine never exits the ‘SYNC’ state, and hence will never lose
cell delineation. This bit is provided for diagnostic purposes only.
Regardless of the programming of this bit, cells are always dropped while the
cell delineation state machine is in the 'HUNT' or 'PRESYNC' states.
Reserved:
This bit must be logic 0 for correct operation.
