Each detected FEBE will cause the FEBE counter to be incremented. The maximum
count is FF
Read Out and Reset
Issuing the MON-8 command RBEF will cause the IEC-Q to respond with the MON-8
indication ABEN consisting of the NEBE counter value in the second byte of the two byte
Monitor Channel indication. For more information about MON-8 codes, refer to "MON-8
Codes", page 228.
