1 The user should verify that all buses and functions run frequencies that are within the supported ranges.
2 Assumes MODCK_HI = 0000.
3 The frequency depends on the value of PCI_MODCK. If PCI_MODCK is high (logic ‘1’), the PCI frequency is
divided by 2 (33 instead of 66 MHz, etc.) and the CPM multiplication factor is multiplied by 2.
4 Core frequency = (60x bus frequency)(core multiplication factor)
5 Bus frequency = CPM frequency / bus division factor
