HCSPASS:

The HCSPASS bit controls the dropping of cells based on the detection of an uncorrectable HCS error. When HCSPASS is a logic zero, cells containing an uncorrectable HCS error are dropped. When HCSPASS is a logic one, cells are passed to the receive FIFO regardless of errors detected in the HCS. Additionally, the HCS verification finite state machine never exits the correction mode.

Regardless of the programming of this bit, cells are always dropped while the cell delineation state machine is in the 'HUNT' or 'PRESYNC' states unless the CCDIS bit in this register is set to logic one.

CCDIS:

The CCDIS bit can be used to disable all cell filtering and cell delineation. All payload data read from the RXCP is passed into its FIFO without the requirement of having to find cell delineation first.

Reserved:

The reserved bits must be programmed to logic zero for proper operation.
