Receive direction ATM side cell data. CX28224 only
supports an 8 bit data path. Thus atmURxData[8:15] are
no-connects.
Parity status signal. In 8 bit Utopia mode, a parity
calculation is performed over atmURxData[7:0] for each
clock cycle of atmUTxClk. Odd parity is used. In 16 bit
Utopia mode, this signal is the parity of atmURxData[15:0].
This signal is optional.
Receive ATM Cell Bus address. This address determines
the source channel of the Receive ATM cells output from
the IMA subsystem and also selects the channel sourcing
the atmURxClAv signal.
