Bit
DATABUFFER[63:0] — R/W. This field is the 8 bytes of the data buffer. Bits 7:0
correspond to least significant byte (byte 0). Bits 63:56 correspond to the most
significant byte (byte 7).
The bytes in the Data Buffer must be written with data before software initiates a write
request. For a read request, the Data Buffer contains valid data when DONE_STS bit
(offset A0, bit 16) is cleared by the hardware, ERROR_GOOD#_STS (offset A0, bit 6)
is cleared by the hardware, and the DATA_LENGTH_CNT field (offset A0, bits 3:0)
indicates the number of bytes that are valid.
Reserved
USB_ADDRESS_CNF — R/W. This 7-bit field identifies the USB device address used
by the controller for all Token PID generation. (Default = 7Fh)
Reserved
USB_ENDPOINT_CNF — R/W. This 4-bit field identifies the endpoint used by the
controller for all Token PID generation. (Default = 01h)
