4.2.3 Reset operation
For the Basic model QCPU, the RUN/STOP/RESET switch of the CPU module is used to switch between the RUN
status and STOP status and to perform RESET operation.
When using the RUN/STOP/RESET switch to reset the CPU module, moving the RUN/STOP/RESET switch to the
reset position will not reset it immediately.
Hold the RUN/STOP/RESET switch in the RESET position until reset processing is complete (the flashing ERR. LED turns
off).
If you release your hand from the RUN/STOP/RESET switch during reset processing (the ERR. LED is flashing), the switch
will return to the STOP position and reset processing cannot be completed.
Perform reset operation with the RUN/STOP/RESET switch as shown in Figure 4.7.
