‡Note: Signal "select condition" is provided. See Figure 4.3-12.
§Note: The SOFTSW1 function is blocked when the ASEQ function is in operation.
Output signal for monitoring
When the state of "select condition" is true, the SOFTSW1 function can issue an output signal
"Select success" at the output-point "S4301_OSD_CSF".
Note: The signal "S4301_OSD_CSF" is the same signal as shown in Figure 4.3-6. If the
input signal "Local-ON-Control" is not true, the SOFTSW1 function returns to the
"Wait for a command" stage.
