Hi Alan,

Please refer: AN12374 PMSM Field-Oriented Control on FRDMKV31F with Hall and Encoder Sensors 
It may help you understand the relationship between FTM PDB ADC

Nice graphic - it's always useful if you can visually show what's happening in the system.

Hi @Alan_LIU 

Can you provide a bit more information?  What do you have working (ie PDB IRQ, ADC configure, ADC start conversion, ADC return conversion value)?  

Could you describe what you want to do?
