Hi all,
I would like to know some questions about TUSB1210-Q1.
When using under the following conditions, the DP/DM is reversed.
This does not change even if register 0x08 is rewritten.
<conditions>
High-speed
Vbus=3.3V
1) The polarity of DP/DM is fine even if it is swapped. Can I use it?
I understand that it can be used with USB3.0, but is it fine with 2.0 as well?
2) Why does it swap?
Does Vbus speed affect polarity? Is it because Vbus=3.3 V?
If the device is sufficiently clocked and unreset, no swap occurs.
Is this a problem caused by the initial operation? I would like to know the cause.
Best Regards,
Ryusuke
