EP1 Buffer Reset

Last Updated: July 01, 2011

Is it possible to reset the EP1 buffers the same way as with the other EP buffers (2,4,6 and 8)?


Unlike the other endpoint buffers, that is, EP2,4,6,8 buffers, which can be reset by the FIFORESET register, the only way to reset an EP1 buffer is by a hard reset. A USB Bus Reset or a CPU reset does not reset the EP1 buffer.
