Hi

 

The LPC546xx datasheet says as follows.

 

 

 

When USB1_AVDD3V3, USB1_AVDDTX3V3 and VDD are connected to 3.3V LDO, is USB1_VBUS 5V tolerant?

 

I have another question about VBUS, If USB1 is only used for host mode, should it be connected to VDD instead of VBUS according to table 5. termination of unused pins?
