Hi, I wonder if there's any limit of endpoint I can use for my usb device.(undecided coldfire product)

Can the same endpoint number be in and out?

thanks!

A quick search through the parametrics and picking the first chip listed, the MCF51JM128, and reading the USB chapter:

16.1.3 USB-FS Features

• USB 1.1 and 2.0 compliant full-speed device controller

• 16-Bidirectional end points

• DMA or FIFO data stream interfaces

Searching Freescales web site for <"bidirectional end point" USB> gets 57 hits. You can download and read from that list.
