Rx User Cell Filter Mask 2
R/W
0xFF
This register, along with the “Rx User Cell Pattern - 2” Register permits the
user to define “User Cell Filtering” criteria for Header byte 2.
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:

This register is only active if the XRT72L74 has been configured to
operate in the “ATM UNI” Mode.
