1… the EPIC-1 starts to search for active MF-channels. Active channels are
MFFIFO Reset.
0… no action
1… resets the MFFIFO and all operations associated with the MF-handler
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
stopped when an active MF-channel has been found or when
OMDR:OMS0 is set to 0.
(except for the search function) within 2 RCL-periods. The MFFIFO is set
into the state "MFFIFO empty", write access enabled and any monitor
data transfer currently in process will be aborted.
