RSR:
Re-synchronization Signal Received. Set when the FLEX decoder detected a re-
synchronization signal and the host configured the FLEX decoder to ignore it via the IRS bit in the
roaming control packet. This bit is cleared when read.
MS1:
Missed Synchronization 1. Set when the FLEX decoder failed to detect the first
synchronization pattern (A /
A
) of a FLEX frame and the FLEX decoder was configured to report
missed frame information via the MFC bit in the roaming control packet. This bit is cleared when
read.
MFI:
Missed Frame Information word. Set when the frame information word is received with an
uncorrectable number of errors and the FLEX decoder was configured to report missed frame
information via the MFC bit in the roaming control packet. This bit is cleared when read.
MS2:
Missed Synchronization 2. Set when the FLEX decoder failed to detect the second
synchronization pattern (C /
C
) of a frame and FLEX decoder was configured to report missed
frame information via the MFC bit in the roaming control packet. This bit is cleared when read.
MBI:
Missed Block Information word 1. Set when at least one of the block information word ones
is received with an uncorrectable number of errors and FLEX decoder was configured to report
missed frame information via the MFC bit in the roaming control packet. This bit is set no more
than once per frame regardless of the number of missed block information word 1’s in the frame.
This bit is cleared when read.
MAW:
Missed Address Word. Set when any address words in the address field is received with
an uncorrectable number of errors and FLEX decoder was configured to report missed frame
information via the MFC bit in the roaming control packet. This bit is set no more than once per
frame regardless of the number of missed address words in the frame. This bit is cleared when
read.
NBU:
Network Bit Update. Set when the NBC bit in the roaming control packet is set and a frame
information word is received with a correctable number of errors. This bit will not be set when the
frame information word is not received due to missing the first synchronization pattern (A /
A
).
This bit is cleared when read.
