8.0 FUNCTIONAL DESCRIPTION
8.1 Power Management Functions
All clocks can be individually enabled or disabled via the 2-wire control interface. On power up,
external circuitry should allow 3 ms for the VCO to stabilize prior to enabling clock outputs to assure
correct pulse widths. When MODE = 0, pins 15 and 46 are inputs (PCI_STOP#), (CPU_STOP#),
when MODE = 1, these functions are not available. A particular clock could be enabled as both the 2-
wire serial control interface and one of these pins indicate that it should be enable.
