Access in multiplexed P-interface mode:
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.

Monitor/Feature Control Registers
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.

Note:Note that if a CFI time slot is selected as receive or transmit time slot of
MF Channel Search On.
0…the search is completed.
1…the EPIC 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.
