This chapter describes the MPC8260 external signals. A more detailed description of 60x
bus signals is provided in Chapter 8, ÒThe 60x Bus.Ó

6.1 Functional Pinout

Figure 6-1 shows MPC8260 signals grouped by function. Note that many of these signals
are multiplexed and this Þgure does not indicate how these signals are multiplexed.

NOTE

A bar over a signal name indicates that the signal is active
lowÑfor example, BB (bus busy). Active-low signals are
referred to as asserted (active) when they are low and negated
when they are high. Signals that are not active low, such as
TSIZ[0Ð1] (transfer size signals) are referred to as asserted
when they are high and negated when they are low.
