PRELIMINARY—SUBJECT TO CHANGE WITHOUT NOTICE
Signal Properties
External reset on the RSTOUT pin is software-assertable independent of chip reset state. There are also
software-readable status flags indicating the cause of the last reset.
1.3.23 GPIO
Like the MC68332, unused bus interface and peripheral pins on the MCF523x can be used as discrete
general-purpose inputs and outputs. These are managed by a dedicated GPIO module that logically groups
all pins into ports located within a contiguous block of memory-mapped control registers.
All of the pins associated with the external bus interface may be used for several different functions. Their
primary function is to provide an external memory interface to access off-chip resources. When not used for
this, all of the pins may be used as general-purpose digital I/O pins. In some cases, the pin function is set by
the operating mode, and the alternate pin functions are not supported. The digital I/O pins on the MCF523x
are grouped into 8-bit ports. Some ports do not use all eight bits. Each port has registers that configure,
monitor, and control the port pins.

Signal Descriptions
This section describes signals that connect off chip. It includes a table of signal properties, and detailed
discussion of the MCF523x signals.
2.1
Signal Properties
Table 2 lists all of the signals grouped by function. The “Dir” column is the direction for the primary
function of the pin.
