* - Support HEXA-Dshot
* - S5_OUT, S6_OUT and DEBUG can be assigned to any combination of LED, software serial and servos
* - S5_OUT, S6_OUT are N-channels, which are only capable of outputs. (E.g., motors, servos, LED strip, PWM outputs.)
* - Input is only available on DEBUG pad. See comment on SOFTSERIAL1 in target.h for details.

// Since PB0 (motor 5) and PB1 (motor 6) are assigned with N-channels, these pin can not handle input.
// Therefore, receiving function of SOFTSERIAL1 can only be assigned to PB3 (DEBUG).
// Default defined here is to use DEBUG for half-duplex serial, suitable for VTX (SmartAudio or Tramp) controls.
// For non-half-duplex requirement (full-duplex or simplex in either direction), assign PB3 to RX and PB0 or PB1 to TX.
