Why are the paired PWM output frequency impacted each other when setting two independent PWM outputs with the BSP driver

[a_ziliu]

This is because the paired PWM output PWM01(PWM23, PWM45) uses the same 8-bit pre-scale. Setting one of the paired PWM output using the driver library will impact the other PWM output frequency . The other paired PWM will be needed if the user wants to use the driver library to generate PWM output with a different frequency.
