PRELIMINARY

The XC223[04]L provides up to 48 I/O lines which are organized into 3 input/output ports
and 1 input port. All port lines are bit-addressable, and all input/output lines can be
individually (bit-wise) configured via port control registers. This configuration selects the
direction (input/output), push/pull or open-drain operation, activation of pull devices, and
edge characteristics (shape) and driver characteristics (output current) of the port
drivers. The I/O ports are true bidirectional ports which are switched to high impedance
state when configured as inputs. During the internal reset, all port pins are configured as
inputs without pull devices active.
All port lines have alternate input or output functions associated with them. These
alternate functions can be programmed to be assigned to various port pins to support the
best utilization for a given application. For this reason, certain functions appear several
times in
All port lines that are not used for alternate functions may be used as general purpose
I/O lines.
