The ratio should be configurable as opposed to hard wired. The bus frequency select straps will be latched on the rising edge of CRESET#. • CRESET# is used as the selection signal for muxing A20M#, IGNNE#, INTR, and NMI with the processor bus/core frequency selection jumpers. A ‘244 buffer maybe used as a mux. The outputs of the ‘244 device are fed to open ...
