Register Name:
Access Type:
Reset Value:
• PENX, X in [0..6]: Pipe X Enable
Set to enable the Pipe X.
Clear to disable the Pipe X, what forces the Pipe X state to inactive and resets the pipe X registers (UPCFGX, UPSTAX,
UPCONX) but not the pipe configuration (ALLOC, PBK, PSIZE).
• PRSTX, X in [0..6]: Pipe X Reset
Set by software to reset the Pipe X FIFO.
This resets the endpoint X registers (UPCFGX, UPSTAX, UPCONX) but not the endpoint configuration (ALLOC, PBK,
PSIZE, PTOKEN, PTYPE, PEPNUM, INTFRQ).
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.
Then, clear by software to complete the reset operation and to start using the FIFO.
