In one embodiment, the bus agent includes a set of snoop status interfaces, an address strobe signal interface, and a bus clock interface for a bus clock signal. The bus agent of this embodiment also includes bus controller logic capable of sensing or asserting one or more of a set of snoop status signals for transaction N on the snoop status interfaces during a snoop phase to start in a bus cycle upon the later of three or more bus clock cycles of the bus clock signal after a beginning of a bus cycle of an the assertion of an address strobe signal for transaction N or two or more bus clock cycles of the bus clock signal after a beginning of a bus cycle in which a most recent snoop phase begins.
