(Output from the CPU Unit to Serial Communications Unit)
The software switches are used for loopback tests, aborts in Protocol Macro Mode, releasing wait sta-
tus, etc. For the details on the software switch functions, refer to Section 5 Serial Gateway and Section
8 Loopback Test.
* The One-shot Trace Switch and Continuous Trace Switch are used for the Serial Communications Unit only when you exe-
cute traces from the CX-Protocol in Protocol Macro Mode. Do not manipulate these switches from a user program.
