State
‘0’ ⇒ normal acceleration from Vmin to Vmax
‘0’
‘1’ ⇒ motion at Vmin without acceleration

Enables entering sleep mode after LIN lost.
See also LIN lost behavior
Triggers autonomous motion after LIN lost at
POR. See also LIN lost behavior
Delays the stall detection after acceleration
‘000’
Duration of the zero current step in number
of PWM cycles.
‘1’ means jitter is added
‘000’
‘0’
‘1’ means stall detection is enabled in case
‘0’
PWM regulator runs at d = 100%
‘0’ means ~ 22 KHz,
‘0’
‘1’ means ~ 44 KHz
