Enabled Flags
ON when a network instruction
(SEND, RECV, CMND, or PMCR)
can be executed with the corre-
sponding port number. Bits 00 to 07
correspond to communications ports
0 to 7.
When two or more network instruc-

vent the instructions from being exe-
cuted simultaneously.
(The flag for a given port is turned
OFF while a network instruction with
that port number is being executed.)
