Linked Channels
The linkage feature allows two channels to share the same Message area, the message
pointer and the message length assumes this property:
Zero value as message length (M_L [4:0] -
base_address + 0x03
) declares the
channel linked to another channel.
The number of this other channel is defined in the message pointer field (M_P [6:0]
-
base_address + 0x02
).
The pointer and the length values for the Message area are defined only once, in
the register set of this other Channel.
Only one level of linkage can be created. This means, (see Figure 36) a Channel k can
be linked to the Channel i but not to Channel j, already defined as linked to Channel i.
All the others can be different between the two channels, for example the ID_Tag.
Figure 36.
Linkage Mechanism
This Message area sharing permits either to optimize the allocation of the 128 bytes of DATA, or to perform some special
communications between the different nodes of the network.
