Field

Description

SLEWDIS

Slew Rate Disable Register. This bit enables/disables slew rate control. If enabled, the Slew Rate Control

and the Slew Rate Control Register has no effect.

0 Slew rate control enabled

1 Slew rate control disabled

14–7

Reserved, should be cleared.

DDR

Data Direction Register. This bit switches the pin between output and input.

0 Pin is an input. The TDO functionality is disabled. All changes on the pad are ignored.

1 Pin is an output. The TDO functionality is enabled.

Reserved, should be cleared.

SLEW

Slew Rate Control Register. This bit selects the slew rate of the pin, and is used only when the pin is selected

as an output and the Slew Rate Enable is set.

0 Fast slew rate selected

1 Slow slew rate selected

3–0

Reserved, should be cleared.
