This 16-bit register contains the PCI status informa-
tion. The function of this register is defined by the
PCI specification and its implementation is required
of all PCI devices. Only some of the bits are used by
this device; those which are not used are hardwired
to 0. Most status bits within this register are desig-
nated as “write clear,” meaning that in order to clear
a given bit, the bit must be written as a 1. All bits
written with a 0 are left unchanged. These bits are
identified in Figure 4 as (R/WC). Those which are
Read Only are shown as (RO) in Figure 4.
