PCI Status Register
The PCI Status Register is used to record status
information for PCI bus related events. The definition
of each of the bits is given in Table 4 and the layout
of the register is shown in Figure 3. Reads to this
register behave normally. Writes are slightly different
in that bits can be reset, but not set. A bit is reset
whenever the register is written, and the data in the
corresponding bit location is a 1. For instance, to
clear bit 14 and not affect any other bits, write the
value 0100_0000_0000_0000b to the register.
