Read/Write Data FIFO

FIFO Mapping
Table 21-1.
Depending on the selected endpoint through the UEPNUM register, the UEPDATX register
allows to access the corresponding endpoint data fifo.

• Endpoint direction configuration
• Summary of Endpoint Configuration:
• Endpoint FIFO reset
The Endpoint 0 is the Default Control Endpoint and will always be configured in Control type.
For Bulk, Interrupt and Isochronous endpoints, the direction is defined with the EPDIR bit of
the UEPCONX register with the following values:
For Control endpoints, the EPDIR bit has no effect.
Do not forget to select the correct endpoint number in the UEPNUM register before access-
ing to endpoint specific registers.
Before using an endpoint, its FIFO will be reset. This action resets the FIFO pointer to its
original value, resets the byte counter of the endpoint (UBYCTLX and UBYCTHX registers),
and resets the data toggle bit (DTGL bit in UEPCONX).
The reset of an endpoint FIFO is performed by setting to 1 and resetting to 0 the corre-
sponding bit in the UEPRST register.
For example, in order to reset the Endpoint number 2 FIFO, write 0000 0100b then 0000
0000b in the UEPRST register.
Note that the endpoint reset doesn’t reset the bank number for ping-pong endpoints.
