Pin assignments and reset states

Signal multiplexing
The following table lists all the MCF5441x pins grouped by function. The Dir column is the direction for the primary function
of the pin only. Refer to the following sections for package diagrams. For a more detailed discussion of the MCF5441x signals,
consult the MCF5441x Reference Manual (MCF54418RM).
NOTE
In this table and throughout this document a single signal within a group is designated
without square brackets (i.e., FB_AD23), while designations for multiple signals within a
group use brackets (i.e., FB_AD[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. Most pins that
are muxed with GPIO default to their GPIO functionality. See the following table for a list
of the exceptions.

1 Current measured at maximum system clock frequency, all modules active, and default drive
strength with matching load.
2 DDR2 interface power is estimated from the Micron DDR2 data sheet. The numbers given in this
table do not include the actual power consumption of the memory itself. The current drawn by the
memory needs to be added to the values in this table and may be several hundred mA.
3 EVDD values depend on the application, with the restrictions that any single pin cannot exceed
25 mA and that the total power does not exceed the thermal characteristics.
