LPC5528 USB1 as full speed device

[tks11111]

Hi All, 

I found a thread that discussed how to use USB1 as a full-speed device.

LPC55S6x USB1 as full speed device - NXP Community

Do I need to change the clock setting if I set the bit 21 of the USB1 device command/status register (DEVCMDSTAT) to 1?
Also, do I need to add any other speed configuration?

Appreciate any help.

Thanks.

BR,

HI tks11111,

There is no need setting clock. 

To set LPC5528 USB1 as full speed device, setting Forced FS bit as 1 is enough.
