Signal Descriptions
2.1 Introduction
This chapter describes MCF5271 signals. It includes an alphabetical listing of signals that
characterizes each signal as an input or output, defines its state at reset, and identifies whether a
pull-up resistor should be used.
these signals interact.
2.1.1 Overview
Figure 2-1
Freescale Semiconductor
shows the block diagram of the MCF5271 with the signal interface.
The terms ‘assertion’ and ‘negation’ are used to avoid confusion when
dealing with a mixture of active-low and active-high signals. The term
‘asserted’ indicates that a signal is active, independent of the voltage
level. The term ‘negated’ indicates that a signal is inactive.
Active-low signals, such as SD_SRAS and TA, are indicated with an
overbar.
