If the ESC control mode is set to “OFF” (external control) in step #14, Pin 1 of TB9 is used for the external control signal.
If the ESC control mode is set to “ON” (internal control) in step #14 and external setpoint is “ON” on step #18, Pin 1 of TB9 is used for the
external setpoint signal.
Step #14 = ON (internal control) &
