These are 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 is cleared
by the hardware, ERROR_GOOD#_STS is cleared by the
hardware, and the DATA_LENGTH_CNT field indicates the
number of bytes that are valid.
Reserved. These bits will return ’0’ when read. Writes will
have no effect.
The hardware updates this field with the received PID for
transactions in either direction. When the controller is writing
data, this field is updated with the handshake PID that is
received from the device. When the host controller is reading
data, this field is updated with the data packet PID (when the
device sent data), or the handshake PID (when the device
NAKs the request). This field is valid when the hardware
clears the GO_DONE#_CNT bit.
The hardware sends this PID to begin the data packet when
sending data to USB (i.e., WRITE_READ#_CNT is asserted).
Software will typically set this field to either DATA0 or DATA1
PID values.
The hardware sends this PID as the Token PID for each USB
transaction. Software will typically set this field to either IN,
OUT or SETUP PID values.
