Address/Data Bus Strobe-0: provides timing for 2x and 4x data on AD[15:0] and
C/BE[1:0]# signals. The agent that is providing the data will drive this signal.
Address/Data Bus Strobe-0 Complement: With AD STB0, forms a differential
strobe pair that provides timing information for the AD[15:0] and C/BE[1:0]#
signals. The agent that is providing the data will drive this signal.
Address/Data Bus Strobe-1: Provides timing for 2x and 4x data on AD[31:16]
and C/BE[3:2]# signals. The agent that is providing the data will drive this signal.
Address/Data Bus Strobe-1 Complement: With AD STB1, forms a differential
strobe pair that provides timing information for the AD[15:0] and C/BE[1:0]# signals
in 4X mode. The agent that is providing the data will drive this signal.
Sideband Strobe: Provides timing for 2x and 4x data on the SBA[7:0] bus. The
AGP master drives it after the system has been configured for 2x or 4x sideband
address mode.
Sideband Strobe Complement: The differential complement to the SB_STB
signal. It is used to provide timing 4x mode.
