POOF Interrupt Status
RUR
0
0: Indicates that the “Change in POOF Condition” Interrupt has not occurred
since the last read of this register.
1: Indicates that the “Change in POOF Condition” interrupt has occurred
since the last read of this register.
NOTE: This bit-field is only active if the XRT72L71is operating in both the
“ATM UNI” and the “PLCP” Modes.

PLOF Interrupt Status
RUR
0
0: Indicates that the “Change in PLOF Condition” Interrupt has not occurred
since the last read of this register.
1: Indicates that the “Change in PLOF Condition” interrupt has occurred
since the last read of this register.
NOTE: This bit-field is only active if the XRT72L71 is operating in both the
“ATM UNI” and the “PLCP” Modes.

FA1 Error Mask
R/W
0x00
The Transmit PLCP Processor block always XORs contents of this register
with the contents of the FA1 byte (within a PLCP frame). This “XORed” value
is then written back into the “FA1” byte field, within each “outbound” PLCP
Frame; prior to transmission. Setting any of these bit-fields to “1” introduces
error in that specific bit, within each “outbound” FA1 byte.
Register must be set to 0x00 for normal operation,
NOTE: This bit-field is only active if the XRT72L71 is operating in both the
“ATM UNI” and the “PLCP” Modes.

The Transmit PLCP Processor block always XORs contents of this register

Frame; prior to transmission. Setting any of these bit-fields to “1” introduces
error in that specific bit, within each “outbound” FA1 byte.
