4.1.
PWM Control Register (PWC)
The PWM Control Register starts/stops the Stepper Motor Controller, sets the PWM prescaler and selects
the operation mode for the generation of the PWM pulse.

[bit9] P[3]: PWM Operating Clock Prescaler bit
P[3] bit, in combination with P[2:0] bits, specifies the clock input signal to the PWM Pulse Generators.
[bit8:7] Reserved: Reserved bits
When writing, always write "0".
When reading, "0" is always read.
[bit6:4] P[2:0]: PWM Operating Clock Prescaler bits
P[2:0] bits, in combination with P[3] bit, specify the clock input signal to the PWM Pulse Generators.
P[3] P[2:0] Description
0 000 PWM Operating clock is equal to the Peripheral clock (CLKP)
0 001 PWM Operating clock is equal to CLKP/4
0 010 PWM Operating clock is equal to CLKP/5
0 011 PWM Operating clock is equal to CLKP/6
0 100 PWM Operating clock is equal to CLKP/8
