How to control the PWM output of the FS23 HSx pins?

Hello,

 In our project, HSx is configured to drive LED lights, with four HS outputs, selecting PWM1, PWM2, PWM3, and PWM3 sources, at a frequency of 200 Hz. During debugging, we found that the interface Sbc_fs23_SetHSxSource() cannot control the corresponding channel's on and off ; instead, we need to use the interface Sbc_fs23_SetTimerPwm() to control them. Below is the configuration of the High side driver:

Additionally, read the configuration registers again , FS0B and LIMP pin levels high, everything is normal. I would like to ask if this control method is correct.

Thanks!
