The Endpoint Index register selects a target endpoint for register access by the
microcontroller. The register consists of 1 byte and the bit allocation is shown in
Table
For example, to access the OUT data buffer of endpoint 1 via the Data Port register,
the Endpoint Index register has to be written first with 02H.
