Clock Configuration Modes
In each clocking mode, the configuration of bus, core, PCI, and CPM frequencies is determined by seven bits during
the power-up reset—three hardware configuration pins (MODCK[1–3]) and four bits from hardware configuration
word[28–31] (MODCK_H). Both the PLLs and the dividers are set according to the selected MPC8280 clock
operation mode as described in the following sections.

of illustration only. Users must select a mode and input bus frequency so that the resulting configuration does not
exceed the frequency rating of the user’s device.
