Descriptions
Loaded Device ID, the device ID number loaded from serial
EEPROM.
Loaded Vendor ID, the vendor ID number loaded from serial
EEPROM.
Descriptions
Status of Parity Error.
1: means that AN983B detected a parity error. This bit will
be set in this condition, even if the parity error response (bit
6 of CR1) is disabled.
Status of System Error.
1: means that AN983B asserted the system error pin.
Status of Master Abort.
1: means that AN983B received a master abort and
terminated a master transaction.
Status of Target Abort.
1: means that AN983B received a target abort and
terminated a master transaction.
Reserved.
Status of Device Select Timing. The timing of the assertion of
device select.
01: means a medium assertion of DEVSEL#
Status of Data Parity Report.
1: when three conditions are met:
AN983B asserted parity error - PERR# or it detected parity
error asserted by other device.
AN983B is operating as a bus master.
AN983B’s parity error response bit (bit 6 of CR1) is enabled.
Status of Fast Back-to-Back
Always 1, since AN983B has the ability to accept fast
back-to-back transactions.
Reserved.
New Capabilities. This bit indicates that whether the AN983B
provides a list of extended capabilities, such as PCI power
management.
