I'm developing a USB device which needs only to run at full speed (12MHz), not high speed (480MHz). I'm using the FRDM-K66F board for development. How can I configure the board's physical USB port to run at full speed?
I understand that there are 2 USB OTG modules on the board (one supporting LS/FS and the other supporting LS/FS/HS), however, I'm confused about how to specify the former for use with the USB-PHY module.
Any help greatly appreciated.
