Cautions 1. To rewrite these registers, set the EP0NKA bit to 1 before reading the register contents,
These registers store the value to be returned in response to the GET_DESCRIPTOR Device request.
These registers can be read or written in 8-bit units. However, data can be written to these registers only
when the EP0NKA bit is set to 1.
