System Clock and CPU Multiplier on HOT-579
For whom like to set up system manually, listed tables show all the System Clock and CPU
Multiplier that HOT-579 can offer.
Table 2-2 shows the System Clock from 50 MHz to 83 MHz.
Table 2-3 shows CPU Multiplier from 1.5X to 5.5X.
Note: Since PCI clock is half of system clock, 75MHz and 83MHz system clocks may
cause PCI clock beyond PCI specification.
