The status of bit 15 of C+1 determines whether the instruction is for a SYSMAC
NET Link System or a SYSMAC LINK System.
Control Data
SYSMAC NET Link Systems The destination port number is always set to 0. Set the destination node number
to 0 to send the data to all nodes. Set the network number to 0 to send data to a
node on the same Subsystem (i.e., network). Refer to the
SYSMAC NET Link
System Manual
for details.
