Yes but this requires external hardware as one of the input pins is shared between these two modes and that the software can only handle one mode or the other at a time. See our application note. Switching modes can be useful in computer controller robots to take over controls via radio in emergency situations. Analog Mode FAQ’s What is the correlation between output voltage and speed/direction The motor output is 0 (stopped) when the analog input is at 2.5V. Full reverse speed is reached when input is at 0V. Full forward speed is reached when input is at 5V. A programmable deadband is provided to keep the motor stopped even as the analog input is not exactly 2.5V. When nothing is connected to the analog input, a pull up and pull down resistor of 47k bring the input to 2.5V so that the motor is stopped.
