Pullup/Pulldown Device Behavior
Most pins of the XE167 feature pullup or pulldown devices. For some special pins these
are fixed; for the port pins they can be selected by the application.
The specified current values indicate how to load the respective pin depending on the
intended signal level.
The shaded resistors shown in the figure may be required to compensate system pull
currents that do not match the given limit values.
