DATABUFFER (DATABUFFER_0): 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 is set 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. Reset
Default = 0.
