Clock Configuration Modes
3.2
PCI Mode
The PCI mode is selected according to three input pins, as shown in Table 12. In addition, note the
following:
NOTE: PCI_MODCK
In PCI mode only, PCI_MODCK comes from the LGPL5 pin and
MODCK_H[0–3] comes from {LGPL0, LGPL1, LGPL2, LGPL3}.
NOTE: Tval (Output Hold)
The minimum Tval = 2 when PCI_MODCK = 1, and the minimum Tval = 1
when PCI_MODCK = 0. Therefore, designers should use clock
configurations that fit this condition to achieve PCI-compliant AC timing.
NOTE
Clock configurations change only after POR is asserted.

1
Because of speed dependencies, not all of the possible configurations in Table 14 are applicable.
2
The user should choose the input clock frequency and the multiplication factors such that the frequency of the CPU
is equal to or greater than 133 MHz (150 MHz for extended temperature parts) and the CPM ranges between 66–233
MHz.
3
Input clock frequency is given only for the purpose of reference. User should set MODCK_H–MODCK_L so that the
resulting configuration does not exceed the frequency rating of the user’s part.
