6.5.3.3 Port C Pull Enable Register (PTCPE)
NOTE
Pull-down devices only apply when using pin interrupt functions, when
corresponding edge select and pin select functions are configured.
6.5.3.4 Port C Slew Rate Enable Register (PTCSE)
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
PTCPE[7:0]
Internal Pull Enable for Port C Bits — Each of these control bits determines if the internal pull-up device is
enabled for the associated PTC pin. For port C 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 C bit n.
1 Internal pull-up device enabled for port C bit n.

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