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.

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.
