7 Clock Configuration Modes
The MPC8280 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

All outputs are measured from the midpoint voltage of the falling/rising edge of t
The output timings are measured at the pins. All output timings assume a purely resistive 50-Ω load. Time-of-flight delays
must be added for trace lengths, vias, and connectors in the system.
The symbols used for timing specifications herein follow the pattern of t
for inputs and t(
device timing (JT) with respect to the time data input signals (D) reaching the valid state (V) relative to the t
(K) going to the high (H) state or setup time. Also, t
signals (D) went invalid (X) relative to the t
reference symbol representation is based on three letters representing the clock of a particular functional. For rise and fall
times, the latter convention is used with the appropriate letter: R (rise) or F (fall).
TRST is an asynchronous level sensitive signal. The setup time is for test purposes only.
