SRC[1:0] 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.
WPE Weak Pullup/Pulldown Enable
This bit controls whether the weak pullup/pulldown devices are enabled/disabled for the pad
connected to this signal.
Note: When a pin is configured as an output, the weak internal pull up/down is disabled
regardless of the WPE or WPS settings in the PCR.
0 Weak pull device disabled for the pad.
1 Weak pull device enabled for the pad.
WPS Weak Pullup/Pulldown Select
This bit controls whether weak pullup or weak pulldown devices are used for the pads connected
to this signal when weak pullup/pulldown devices are enabled.
0 Weak pulldown selected
1 Weak pullup selected
