Automatic PWM Generator
The TLE75080-EMH has two independent automatic PWM generator implemented. Each PWM generator can be
assigned to one or more channels, and can be programmed with a different duty cycle and frequency.
Both PWM generator refer to a base frequency f_INT generated by an internal oscillator. This base frequency can
be adjusted using HWCR_PWM.ADJ bits as described in Table 9.
