Dear sir/ms.

I have made a program in codewarrior 10.7,the cpu is mc56f84789. In PE, I have met two problems, they are follows.

1. I have added a flash module in my program,but I can not read or write the flash correctly, can you give me an example that how I read or write the flash? It is wonderful if you can give me a video.

2. I have added eFlexPWM module, there is a fault in my program when the PWM fault pin is high level. If there is a fault, sometimes enter the fault interrupt,sometimes does not enter the fault interrupt, how can I set the fault pin to enter the fault interrupt ? or which options can I set to enter the fault interrupt? can you give me an example? It is wonderful if you can give me a video.

Best regards.

Hi, Guo,

Regarding the flash writting/reading, I have only the code based on PE, I attach it, hope it can help you.

Regarding the fault of eFlexPWM, the interrupt index 77 is the eFlexPWMA fault vector, the FLVL bits in PWMA_FCTRLn set the fault logic, the FIE bits set the faultx pin interrupt enable, the PWMA_FAULT bits in INTC_IPR8 set the interrupt priority.

Hope it can help you
