Signal Descriptions
This chapter describes the MPC561/MPC563 microcontroller’s external signals. It contains a description
of individual signals, shows their behavior, shows whether the signal is an input or an output, and indicates
signal multiplexing.
NOTE
A bar over a signal name indicates that the signal is active-low—for
example, TA (transfer acknowledge). 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 ADDR[8:31] (address bus signals) and
DATA[0:31] (data bus signals) are referred to as asserted when they are high
and negated when they are low.
Refer to
Appendix F, “Electrical Characteristics
,” and
Appendix G, “66-MHz Electrical Characteristics
,”
for detailed electrical information for each signal.
