For example, to access the OUT data buffer of endpoint 1 using the Data Port register, the
Endpoint Index register must be written first with 02h.
Remark: The Endpoint Index register and the DMA Endpoint register must not point to the
same endpoint, irrespective of IN and OUT.
Table 110. Endpoint Index register (address 022Ch) bit description
Table 111. Addressing of endpoint buffers
The Control Function register performs the buffer management on endpoints. It consists
of 1 byte, and the bit configuration is given in
validate any enabled data endpoint. Before accessing this register, the Endpoint Index
register must first be written to specify the target endpoint.
