Field : devspd

Device Speed (DevSpd)

Indicates the speed at which the application requires the core to

enumerate, or the maximum speed the application can support.

However, the actual bus speed is determined only after the chirp

sequence is completed, and is based on the speed of the USB

host to which the core is connected. See “Device Initialization”

2'b00: High speed (USB 2.0 PHY clock is 30 MHz or 60 MHz)

2'b01: Full speed (USB 2.0 PHY clock is 30 MHz or 60 MHz)

2'b10: Low speed (USB 1.1 transceiver clock is 6 MHz). If

you select 6 MHz LS mode, you must do a soft reset.
