MPC8280 PowerQUICC II Family Hardware Specifications
MOTOROLA
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.
7.1
Local Bus Mode
Table 15 lists clock configurations for the MPC8280 in local bus mode. The frequencies listed are for the
purpose 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.
NOTE
Clock configurations change only after PORESET is asserted.
