4.2.5.1 MF-Channel Active Indication Register (MFAIR)
Access in demultiplexed P-interface mode:
Access in multiplexed P-interface mode:
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.

Channel Type A (B); these bits determine the bandwidth of the channel and
the position of the relevant bits in the time slot according to the table below.

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.
