high current in the internal ESD protection diodes. The rise times on the power supplies should be slower than 500 us to avoid
turning on the internal ESD protection clamp diodes.
3.3.2
Power Down Sequence
If IVDD/PLLVDD are powered down first, sense circuits in the I/O pads cause all output drivers to be in a high impedance state.
There is no limit on how long after IVDD and PLLVDD power down before EVDD or SDVDD must power down. IVDD should
not lag EVDD, SDVDD, or PLLVDD going low by more than 0.4 V during power down or there is undesired high current in the
ESD protection diodes. There are no requirements for the fall times of the power supplies.
The recommended power down sequence is as follows:
1.
Drop IVDD/PLLVDD to 0 V.
2.
Drop EVDD/SDVDD supplies.

Signal Multiplexing
The following table lists all the MCF532x pins grouped by function. The Dir column is the direction for the primary function
of the pin only. Refer to Section 7, “Package Information,” for package diagrams. For a more detailed discussion of the
MCF532x signals, consult the MCF5329 Reference Manual (MCF5329RM).
NOTE
In this table and throughout this document, a single signal within a group is designated
without square brackets (i.e., A23), while designations for multiple signals within a group
use brackets (i.e., A[23:21]) and is meant to include all signals within the two bracketed
numbers when these numbers are separated by a colon.
NOTE
The primary functionality of a pin is not necessarily its default functionality. Pins that are
muxed with GPIO default to their GPIO functionality.
