Writing a one to this bit will reset the endpoint n FIFO prior to any other operation, upon hardware reset or when a USB bus
All the endpoint mechanism (FIFO counter, reception, transmission, etc.) is reset apart from the Data Toggle Sequence field
The endpoint configuration remains active and the endpoint is still enabled.
Writing a zero to this bit will complete the reset operation and start using the FIFO.
This bit is cleared upon receiving a USB reset.
1: The endpoint n is enabled.
0: The endpoint n is disabled, what forces the endpoint n state to inactive (no answer to USB requests) and resets the endpoint
reset has been received. This resets the endpoint n registers (UECFGn, UESTAn, UECONn) but not the endpoint
configuration (ALLOC, EPBK, EPSIZE, EPDIR, EPTYPE).
(DTSEQ) which can be cleared by setting the RSTDT bit (by writing a one to the RSTDTS bit).
n registers (UECFGn, UESTAn, UECONn) but not the endpoint configuration (ALLOC, EPBK, EPSIZE, EPDIR, EPTYPE).
