FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
DIR: L = CW, H = CCW; Hall Signals: L = (Hx + < Hx-), H = (Hx + > Hx-); PWM: L = Enable, H = Disable
RUN = L, Internal Reset = H, All protections = “L” (Negated).
When PWM is Disabled (H), the output will be in slow decay mode on the high-side with Synchronous Rectification.
