AD Bus Strobe-0: Provides timing for 2x and 4x clocked data on AD[15:0] and
C/BE[1:0]#. The agent that is providing data drives this signal.
AD Bus Strobe-0 Complement: The differential complement to the AD_STB0 signal. It
is used to provide timing for 4x clocked data.
AD Bus Strobe-1: Provides timing for 2x and 4x clocked data on AD[31:16] and
C/BE[3:2]#. The agent that is providing data drives this signal.
AD Bus Strobe-1 Complement: The differential complement to the AD_STB1 signal. It
is used to provide timing for 4x clocked data.
Sideband Strobe: Provides timing for 2x and 4x clocked data on the SBA[7:0] bus. The
AGP master drives it after the system has been configured for 2x or 4x clocked sideband
address delivery.
Sideband Strobe Complement: The differential complement to the SB_STB signal. It is
used to provide timing for 4x clocked data.
