PRODUCTION DATA
The serial-bus data register is used to read and write data on the serial-bus interface. When writing data to the serial bus, this register must be written before writing to the serial-bus address register to initiate the cycle. When reading data from the serial bus, this register will contain the data read after the REQBUSY (bit 5 serial-bus control register) bit is cleared. This register is an alias for the serial-bus data register in the PCI header. This register shall only be reset by FRST.
