The SPEED input pin can be configured to operate as an analog input (SpdCtrlMd = 0).
When configured for analog mode, the voltage range on the SPEED pin can be varied from 0 to V3P3. If
SPEED > VANA_FS, the speed command is maximum. If VANA_ZS ≤ SPEED < VANA_FS the speed command changes linearly according to the magnitude of the voltage applied at the SPEED pin. If SPEED < VANA_ZS the speed command is to stop the motor. Figure 28 shows the speed command when operating in analog mode.
