USB VBUS register's function on AM3352

Guru 16800 points


Hello,

There are some registers which shows the same description and the USB interrupt indication in TRM of AM335x.
For example, USB1IRQSTAT1 and USB1IRQSTATRAW1 seem the same function.
Which should I used to detect the VBUS error?
What is the difference between these register?

Best Regards,

Nomoto
