MCSPTE1AK144_BLDC_6Step with hall sensor feedback

[sarwath]

Hello Community,

I am working on the BLDC motor controlling by Hall sensor feedback. I download the NXP sample code for the same. In actuate_s32k.c file, the 6 step commutation is given. my doubt is  for this comutation ui8FTM3OutmaskVal[0][0] and ui16FTM3SwOctrlVal[0][0] which two channel PWM is driven among 6 channels. How to find the channel with commutation input.

Thanks in advance,

Sarwath
