6.5.4.3

Port D Pull Enable Register (PTDPE)

NOTE

Pull-down devices only apply when using pin interrupt functions, when

corresponding edge select and pin select functions are conﬁgured.

6.5.4.4

Port D Slew Rate Enable Register (PTDSE)

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

PTDPE[7:0]

Internal Pull Enable for Port D Bits — Each of these control bits determines if the internal pull-up or pull-down

device is enabled for the associated PTD pin. For port D pins that are conﬁgured as outputs, these bits have no

effect and the internal pull devices are disabled.

0 Internal pull-up/pull-down device disabled for port D bit n.

1 Internal pull-up/pull-down device enabled for port D bit n.

PTDSE[7:0]

Output Slew Rate Enable for Port D Bits — Each of these control bits determines if the output slew rate control

is enabled for the associated PTD pin. For port D pins that are conﬁgured as inputs, these bits have no effect.

0 Output slew rate control disabled for port D bit n.

1 Output slew rate control enabled for port D bit n.
