Signal Description
USB_Clk
In
Interface clock—All interface signals are synchronous to USB_Clk
USB_Data[7:0]
I/O
Bidirectional data bus, driven low by the link during idle—Bus ownership is determined by the
direction
USB_Dir
In
Direction—Control the direction of the data bus
USB_Stp
Out
Stop—The link asserts this signal for one clock cycle to stop the data stream currently on the bus
USB_Nxt
In
Next—The PHY asserts this signal to throttle the data
