Figure 30-14. Endpoint Activation Algorithm

Endpoint Reset
Endpoint Activation
An endpoint can be reset at any time by setting its EPRSTX 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 UESTAX 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 setting the RSTDT bit (by setting
the RSTDTS bit).
In the end, the firmware has to clear the EPRSTX bit to complete the reset operation and to start
using the FIFO.
The endpoint is maintained inactive and reset (see
details) as long as it is disabled (EPENX = 0). The Data Toggle Sequence bit-field (DTSEQ) is
also reset.
The algorithm represented on
As long as the endpoint is not correctly configured (CFGOK = 0), the controller does not
acknowledge the packets sent by the host to this endpoint.
The CFGOK bit is set by hardware only if the configured size and number of banks are correct
compared to their maximal allowed values for the endpoint (see
the maximal FIFO size (i.e. the DPRAM size).
