8MHz

7. Question : (TCO #6) In case of center-aligned PWM, which formula can be used for the duty cycle of the output waveform?

Duty Cycle = [(PWMPERx – PWMDTYx) / PWMPERx] * 100%

Duty Cycle = [PWMDTYx / PWMPERx] * 100%

Duty Cycle = PWMDTYx 100%

Both A or B (depends on PPOLx)

8. Question : (TCO #6) In case of center-aligned PWM, which formula can be used for the PWM frequency?

PWMx frequency = Clock (A, B, SA, or SB) / PWMPERx

PWMx frequency = Clock (A, B, SA, or SB) / (2 * PWMPERx)

PWMx frequency = Clock (A, B, SA, or SB) / (4 * PWMPERx)

PWMx frequency = Clock (A, B, SA, or SB) / (3 * PWMPERx)
