Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Endpoint Index
This bit field configures which endpoint is accessed when reading or
writing to one of the USB controller's indexed registers. A value of 0x0
corresponds to Endpoint 0 and a value of 0x7 corresponds to Endpoint
7.
