82C85 March 1997 CMOS Static Clock Controller/Generator Description The Intersil 82C85 Static CMOS Clock Controller/Generator provides complete control of static CMOS system operating modes and supports full speed, slow, stop-clock and stop-oscillator operation. While directly compatible with the Intersil 80C86 and 80C88 16-bit Static CMOS Microprocessor Family, the 82C85 can also be used for general system clock control. For static system designs, separate signals are provided on the 82C85 for stop (S0, S1, S2/STOP) and start (START) control of the crystal oscillator and system clocks. A single control line (SLO/FST) determines 82C85 fast (crystal/EFI frequency divided by 3) or slow (crystal/EFI frequency divided by 768) mode operation.
