USB data FIFO map: question of newbie

Posted on April 10, 2013 at 19:56

Hi all,

As I said previously, I am learning USB and reading and reading again the USB spec.

I want to understand the USB dta FIFO.

In fact in table ''Data FIFO access register map'', there is an address range.

For example for EP0; the range is ''

0x1000–0x1FFC

''

My question is: as it is a FIFO should be a set at a single address for read/write (as an example ''0x1000'') and not a range?

Thanks
