S/UNI®-JET Data Sheet
Released
BEI
The BEI bit indicates that one or more bit errors have been detected since the last time this
register was read. When BEI is set to logic one, at least one bit error has been detected. BEI is
set to logic zero when this register is read.
XFERI
The XFERI bit indicates that a transfer of pattern detector data has occurred. A logic one in
this bit position indicates that the pattern receive registers, the bit counter holding registers
and the error counter holding registers have been updated. This update is initiated by writing
to one of the pattern detector register locations, or by writing to the S/UNI-JET Identification,
Master Reset, and Global Monitor Update Register (006H). XFERI is set to logic zero when
this register is read.
OVR
The OVR bit is the overrun status of the pattern detector registers. A logic one in this bit
position indicates that a previous transfer (indicated by XFERI being logic one) has not been
acknowledged before the next accumulation interval has occurred and that the contents of the
pattern receive registers, the bit counter holding registers and the error counter holding
registers have been overwritten. OVR is set to logic zero when this register is read.
