Description
Slew Rate Control
This field controls the slew rate control output signals from the SIUL. The output signals are driven
to the value of this field. The actual slew rates are defined by the implementation of the pad
devices for a given SoC.
Note: For low-power modes, keeping these bits asserted may result in more leakage. It is
recommended to not drive these bits during low-power modes.
Weak Pull Up/Down Enable
This bit controls whether the weak pull up/down devices are enabled/disabled for the pad
connected to this signal.
1: Weak pull device enabled for the pad.
0: Weak pull device disabled for the pad.
Weak Pull Up/Down Select
This bit controls whether weak pull up or weak pull down devices are used for the pads connected
to this signal when weak pull up/down devices are enabled.
1: Weak pull-up selected
0: Weak pull-down selected
