1 The user should verify that all buses and functions run frequencies that are within the supported ranges.
2 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.
3 66 MHz congurations are required for input clock frequencies higher than 50 MHz;
33 MHz congurations are required for input clock frequencies below 50 MHz.
4 Core frequency = (60x bus frequency)(core multiplication factor)
5 Bus frequency = CPM frequency / bus division factor
6 In this mode, PCI_MODCK must be “1”.
7 In this mode the Core PLL is bypassed (core frequency equals bus frequency; for debug purpose only).
