5.1.1.4.23 MF-Channel Active Indication Register (MFAIR)
Access: read/write
Reset value: 00
This register is only used in IOM-2 applications (active handshake protocol) in order to
identify active monitor channels when the “Search for active monitor channels”
command (CMDR:MFSO) has been executed.

5.1.1.4.24 MF-Channel Subscriber Address Register (MFSAR)
Access: read/write
Reset value: xx
The exchange of monitor data normally takes place with only one subscriber circuit at a
time. This register serves to point the MF-handler to that particular CFI time-slot.

0…the search is completed.
1…the EPIC-1 is still busy looking for an active channel.
Subscriber Address 5…0; after an ISTA:MAC-interrupt these bits point to the
port and time-slot where an active channel has been found. The coding is
identical to MFSAR:SAD5…SAD0.
and OMDR:MFPS control the MF-channel transfer as indicated in
Table 5-44.
Subscriber Address 5..0; these bits define the addressed subscriber. The
CFI time-slot encoding is similar to the one used for Control Memory
accesses using the MAAR-register (Table 5-41 and Table 5-42):
