4.2.5.2 MF-Channel Subscriber Address Register (MFSAR)
Access in demultiplexed P-interface mode:
Access in multiplexed P-interface mode:
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.
MFTC1..0
SAD5..0
CFI time slot encoding of MFSAR derived from MAAR:
MAAR:MA7 selects between upstream and downstream CM blocks. This information is
not required since the transfer direction is defined by CMDR (transmit or receive).
MAAR:MA0 selects between even and odd time slots. This information is also not
required since MF channels are always located on even time slots.
MFSAR: MFTC1 MFTC0 SAD5

MF Channel Transfer Control 1..0; these bits, in addition to CMDR:MFT1,0
and OMDR:MFPS control the MF channel transfer as indicated in table 5.
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 (tables 3 and 4):
