1…resets the signaling FIFO within 2 RCL-periods, i.e. all entries and the
MF-channel Transfer Control Bits 1,0; these bits start the monitor transfer
enabling the contents of the MFFIFO to be exchanged with the subscriber
circuits as specified in MFSAR. The function of some commands depends
furthermore on the selected protocol (OMDR:MFPS). Table 5-44
summarizes all available MF-commands.

characterized by an active MX-bit (logical 0) sent by the remote
transmitter. If such a channel is found, the corresponding address is
stored in MFAIR and an ISTA:MAC-interrupt is generated. The search is

into the state “MFFIFO empty”, write access enabled and any monitor
data transfer currently in process will be aborted.
