11.5 ADC input potentiometer
There is a rotary variable resistor R293 on the EVB which routes a voltage between 0v and PER_HVA (3.3 V or 5.0 V). This
is useful for quick ADC testing.
11.6 Stepper Motor peripheral
The chip has one Stepper Motor Controller (SMC) module capable of driving up to six stepper motors for instrument cluster
gauges. Each stepper motor is driven by four outputs to drive two coils. Control of this module will be typically, but not
exclusively, by the Cortex M0+ IO processor subsystem.
The Stepper Motor Controller (SMC) block is a PWM motor controller suitable for driving small stepper and air core motors
used in instrumentation applications. The module can also be used for other motor control or PWM applications that match
the frequency, resolution and output drive capabilities of the module.
The SMC has 12 PWM channels associated with two pins each (24 pins in total).
