Clock Configuration Modes
3
The MPC8250 has three clocking modes: local, PCI host, and PCI agent. The clocking mode is set
according to three input pins—PCI_MODE, PCI_CFG[0], PCI_MODCK—as shown in
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 MPC8250 clock operation mode as described in the following sections.

The UPM machine outputs change on the internal tick determined by the
memory controller programming; the AC specifications are relative to the
internal tick. Note that SDRAM and GPCM machine outputs change on
CLKin’s rising edge.
Clock configurations change only after POR is asserted.
