Hello. I have a question about 56F84789. When I use 56F84789,  I configure the bean PWMMC to generator PWMA and PWMB in Codewarrior. However, I can observe PWMA signal ,but I cannot find PWMB signal. If there are some differences between PWMA and PWMB.Thank you.

Hi, Liu,

The main difference of PWMA and PWMB is that the PWMB does not support nano-edge placement feature, the PWMA module supports the nano-edge placement feature. For the other feature, they are the same.

If you still have issue, pls post your project so that we can have a review.

Hi!Rong.

I add the project in the attachment. And I found that the register PWMB_FSTS0 =0x0800.

I think the bean that configures PWMB may have some mistakes, pls look at the project and find the cause or give a project that uses bean configures PWMB.

Hoping for your reply.

Hi,

I have checked the PE configuration, a lof items are not set. I help you set all the PE configuration, now it is okay.

You can check the PWMB signals from GPIOG0,GPIOG1,GPIOG2,GPIOG3 and GPIOE8 and GPIOE9 pins, if you have TWR-8400 board, you can test the pin4,6,21,22,23,24 of J503 connector.

I attach the project which is based on your project.

Thank you for your help. According to the project you attached, I found that Fault channel is configured by no instead of yes. Then I changed the configuration, PWMB worked.Thank you again.
