TM4C123GH6PM: Can I modify the USB endpoint FIFO size

Rick Ni

Part Number: TM4C123GH6PM

Hi.

I'm reading the RM for USB controlller. In 18.4.2 Endpoint Configuration, It's said that the total FIFO RAM available is 2 Kbytes with the first 64 bytes reserved for endpoint
0 . Can I modify or enlarge the size? And which register can be set?

Thanks.

The 2K byte size is a hardware implementation. You cannot increase the size.

Thanks, Bob

Can I increase the first 64KB reserved for endpoint to 128KB?

If you mean from 64 bytes to 128 bytes, yes.
