by 2 (33 instead of 66 MHz, etc.) and the CPM multiplication factor is multiplied by 2. Refer to
MODCK[1–
The frequency depends on the value of PCI_MODCK. If PCI_MODCK is high (logic ‘1’), the PCI frequency is divided
MODCK_H
Assumes MODCK_HI = 0000.
Core frequency = (60x bus frequency)(core multiplication factor)
Bus frequency = CPM frequency / bus division factor
