Clock Configuration Modes
NOTE
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 Configuration Modes
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 Table 12.
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.
NOTE
Clock configurations change only after POR is asserted.
3.1
Local Bus Mode
Table 13 shows the eight basic clock configurations for the MPC8250. Another 49 configurations are
available by using the configuration pin (RSTCONF) and driving four pins on the data bus.
