Accuracy of general purpose timer in i.MX6Q USB

Hi,

 

According to the i.MX6Q reference manual, there is a general purpose timer in the USB module.
So I want to make sure the relationship between SOF(125us) and this timer(1~1677215us).

 

Those two are completely synchronized?

 

For example, if I programmed the timer duration as 1000us, the interrupt will constantly generate each 8 micro frames(8x125us)?

 

Can anybody help me?

Thanks.
