(5)Status (B)

The status during the execution of a SEND or RECV instruction and after that instruction terminates is stored in the register shown at B. When TermSTS = 0BH, the detailed information (S20LP-station error information) will be loaded into the registers indicated at location B + 1.

The following figure shows the structure of the status information (register B) and following tables (TermSTS (Part1 and Part2) and detailed information) show the detailed information (register B +1).

(Note 6) The user program must set bits C and D to 0 before first activating a SEND/RECV instruction. Failure to do so will cause the SEND/RECV instruction to not complete. Also, do not write to the status during instruction execution. This will cause the SEND/RECV instruction to not complete.
