Motor Controller (MC10B8CV1)
9.1
The block MC10B8C is a PWM motor controller suitable to drive instruments in a cluster configuration
or any other loads requiring a PWM signal. The motor controller has eight PWM channels associated with
two pins each (16 pins in total).
9.1.1
The MC10B8C includes the following features:
9.1.2
9.1.2.1
9.1.2.1.1
The motor controller can be configured to either 11- or 7-bits resolution mode by clearing or setting the
FAST bit. This bit influences all PWM channels. For details, please refer to
Controller Duty Cycle
9.1.2.1.2
Dither function can be selected or deselected by setting or clearing the DITH bit. This bit influences all
PWM channels. For details, please refer to

10/11-bit PWM counter
11-bit resolution with selectable PWM dithering function
7-bit resolution mode (fast mode): duty cycle can be changed by accessing only 1 byte/output
Left, right, or center aligned PWM
Output slew rate control
This module is suited for, but not limited to, driving small stepper and air core motors used in
instrumentation applications. This module can be used for other motor control or PWM
applications that match the frequency, resolution, and output drive capabilities of the module.
