6.5.6.3 Port F Pull Enable Register (PTFPE)
NOTE
Pull-down devices only apply when using pin interrupt functions, when
corresponding edge select and pin select functions are configured.
6.5.6.4 Port F Slew Rate Enable Register (PTFSE)
Note: Slew rate reset default values may differ between engineering samples and final production parts. Always initialize slew
rate control to the desired value to ensure correct operation.

Field Description
7:0
PTFPE[7:0]
Internal Pull Enable for Port F Bits — Each of these control bits determines if the internal pull-up device is
enabled for the associated PTF pin. For port F pins that are configured as outputs, these bits have no effect and
the internal pull devices are disabled.
0 Internal pull-up device disabled for port F bit n.
1 Internal pull-up device enabled for port F bit n.

PTFSE[7:0]
Output Slew Rate Enable for Port F Bits — Each of these control bits determines if the output slew rate control
is enabled for the associated PTF pin. For port F pins that are configured as inputs, these bits have no effect.
0 Output slew rate control disabled for port F bit n.
1 Output slew rate control enabled for port F bit n.
