When I use the eFlexPWM submodule 0 of the S32K396 to generate complementary PWM, the PWMA channel has output, but the PWMB channel does not. However, when I use PWMB to output PWM separately, the PWMB channel outputs normally. Below are my configurations and code in the S32DS.

Could you please tell me how to configure it so that the complementary channel PWMB outputs normally? Thank you.
