[quote user="fan Linlin"]I didn't find the option about 32-bit align set .Is there something wrong about my compiler set?[/quote]
I'm not sure I understand. I think you expect invVoltPwrAB and invVoltPwrBC to be right next to each other, and not have a 2-byte hole in between them. I presume I am correct about that.
I am unable to reproduce this behavior. I'd appreciate if you would package up your CCS project and attach it to your next post.
Thanks and regards,
