PTKPE[7:0]
Internal Pull Enable for Port K Bits â Each of these control bits determines if the internal pull-up device is
enabled for the associated PTK pin. For port K pins that are conï¬gured as outputs, these bits have no effect and
the internal pull devices are disabled.
0 Internal pull-up device disabled for port K bit n.
1 Internal pull-up device enabled for port K bit n.
NOTE
Pull-down devices only apply when using pin interrupt functions, when
corresponding edge select and pin select functions are conï¬gured.

Output Slew Rate Enable for Port K Bits â Each of these control bits determines if the output slew rate control
is enabled for the associated PTK pin. For port K pins that are conï¬gured as inputs, these bits have no effect.
0 Output slew rate control disabled for port K bit n.
1 Output slew rate control enabled for port K bit n.
Note: Slew rate reset default values may differ between engineering samples and ï¬nal production parts. Always initialize slew
rate control to the desired value to ensure correct operation.
