Writing a one to this bit will reset the Pipe n FIFO.
This resets the endpoint n registers (UPCFGn, UPSTAn, UPCONn) but not the endpoint configuration (ALLOC, PBK, PSIZE,
All the endpoint mechanism (FIFO counter, reception, transmission, etc.) is reset apart from the Data Toggle management.
The endpoint configuration remains active and the endpoint is still enabled.
Writing a zero to this bit will complete the reset operation and allow to start using the FIFO.
Writing a one to this bit will enable the Pipe n.
Writing a zero to this bit will disable the Pipe n, what forces the Pipe n state to inactive and resets the pipe n registers (UPCFGn,
PTOKEN, PTYPE, PEPNUM, INTFRQ).
