Chapter 9 Motor Controller (MC10B8CV1)
The motor controller channel frequency of operation can be calculated using the following formula if
DITH = 1:

different peripheral bus clock frequencies and the prescaler value.

In order to prevent large peak current draw from the motor power supply, selectable delays can be used to
stagger the high logic level to low logic level transitions on the motor controller outputs. The timing delay,
t
selectable between 0, 1, 2, or 3 motor controller timer counter clock cycles.

d
, is determined by the CD[1:0] bits in the corresponding channel control register (MCMCx) and is
shows examples of the motor controller channel frequencies that can be generated based on
Output Switching Delay
Both equations are only valid if MCPER is not equal to 0. M = 1 for left or
right aligned mode, M = 2 for center aligned mode.
Due to the selectable slew rate control of the outputs, clipping may occur on
short output pulses.
A PWM channel gets disabled at the next timer counter overflow without
notice of the switching delay.
