Description
31:0 DATA RW 0x0 Configuration Data. A read from this field will return the configu-
ration space register value pointed to by the ECFGADDR regis-
ter. A write to this field will update the contents of the
configuration space register pointed to by the ECFGADDR regis-
ter with the value written. For both reads and writes, the byte
enables correspond to those used to access this field.
When the ECFGADDR register points to the ECFGDATA regis-
ter, then reads from ECFGDATA return zero and writes are
ignored. When the ECFGADDR register points to itself, writes to
the ECFGDATA register modify the contents of the ECFGADDR
register.
SMBus reads of this field return a value of zero and SMBus
writes have no effect.
