Any “1” in this register, configures the Receive Cell Processor to make the
comparison between the corresponding bit-field within Header byte 2 and
the contents of the “Rx User Cell Pattern - 2” register.
Any “0” in this register, configures the Receive Cell Processor to NOT per-
form this comparison:
NOTE: This register is only active if the XRT72L71 has been configured to
operate in the “ATM UNI” Mode.
