Endpoint reset
Endpoint activation
An endpoint can be reset at any time by writing a one to the Endpoint n Reset (EPRSTn) bit in
the UERST register. This is recommended before using an endpoint upon hardware reset or
when a USB bus reset has been received. This resets:
Note that the interrupt sources located in the UESTAn register are not cleared when a USB bus
reset has been received.
The endpoint configuration remains active and the endpoint is still enabled.
The endpoint reset may be associated with a clear of the data toggle sequence as an answer to
the CLEAR_FEATURE USB request. This can be achieved by writing a one to the Reset Data
Toggle Set bit in the Endpoint n Control Set register (UECONnSET.RSTDTS).(This will set the
Reset Data Toggle (RSTD) bit in UECONn).
In the end, the user has to write a zero to the EPRSTn bit to complete the reset operation and to
start using the FIFO.
The endpoint is maintained inactive and reset (see
it is disabled (EPENn is written to zero). DTSEQ is also reset.
