A213 A213.00
to
A213.07 Explicit Com-
munications
Error Flag Turn ON when an error occurs in
executing an Explicit Message
Instruction (EXPLT, EGATR, ESATR,
ECHRD, or ECHWR).
Bits 00 to 07 correspond to commu-
nications ports 0 to 7.
The corresponding bit will turn ON
both when the explicit message can-
not be sent and when an error
response is returned for the explicit
message.
The status will be maintained until
the next explicit message communi-
cation is executed. The bit will always
turn OFF when the next Explicit Mes-
sage Instruction is executed. ON: Error end
OFF: Normal
end

Flags after
Network Com-
munications
Finished Each flag will turn ON for just one
cycle after communications have
been completed. Bits 00 to 07 corre-
spond to ports 0 to 7. Use the Used
Communications Port Number stored
in A218 to determine which flag to
access.
Note These flags are not effective
until the next cycle after the
communications instruction is
executed. Delay accessing
them for at least one cycle.

Flags after
Network Com-

Error Each flag will turn ON for just one
cycle after a communications error
occurs. Bits 00 to 07 correspond to
ports 0 to 7. Use the Used Communi-
cations Port Number stored in A218
to determine which flag to access.
Determine the cause of the error
according to the Communications
Port Completion Codes stored in
A203 to A210.
Note These flags are not effective
until the next cycle after the
communications instruction is
executed. Delay accessing
them for at least one cycle.

Code Storage
Address The completion code for a communi-

stored at the address with the I/O
memory address given in these
words.
Place this address into an index reg-
ister and use indirect addressing
through the index register to read the
communications completion code. I/O memory
