external capacitor connection for adaptive communication delay timing copy
external capacitor connection for start-up oscillator
external capacitor connection for timing
non-inverting input of the transconductance amplifier
inverting input of the transconductance amplifier
transconductance amplifier output (open collector)
driver output 3
not connected
input from the star point of the motor coils
ground (0 V) motor supply return for output stages
