Serial Data Format
10-Bit Serial Data
Ifx: Current control for channels E and F (0 = Enable; 1 = Disable)
Pms: Channel switching of the PMW input (0 = channel E; 1 = channel F)
Off: Chop-off count (0 = 5 internal clock cycles, 1 = 3 internal clock cycles)
Swx: Turns on/off SW1 and SW2 (0 = off; 1 = on)
Vc: Channel E control mode (0 = External PWM control; 1 = Internal FLL speed control)
Reverse brake: Sets the reverse brake time to be 2.048 ms × specified value
Forced commutation time for startup: Full drive for a period of 2.048 ms × specified value after startup
Charge pump gain: These 3 bits specify the gain of the charge pump to one of the 8 levels between ±10 µA to
Career frequency: These 2 bits specify the triangular wave frequency to one of the frequencies: 20 kHz,
Speed target: These 4 bits specify the speed target value to any of the 16 speed between 250 Hz to 1750 Hz in
Constant-current ramp-up rate: Controls the current ramp-up slope for channel F by changing the number of
