Port E Data Direction—
This bit determines whether the associated pin is an input or output.
1 Associated pin configured as output
0 Associated pin configured as input
BKGD pin Pullup Enable—Enable pullup device on pin
This bit configures whether a pullup device is activated, if the pin is used as input. If a pin is used as output this bit
has no effect. Out of reset the pullup device is enabled.
1 Pullup device enabled
0 Pullup device disabled
Port E Pulldown Enable—Enable pulldown devices on all port input pins
This bit configures whether a pulldown device is activated on all associated port input pins. If a pin is used as output
or used with the CPMU OSC function this bit has no effect. Out of reset the pulldown devices are enabled.
1 Pulldown devices enabled
0 Pulldown devices disabled
Port D Pullup Enable—Enable pullup devices on all port input pins
This bit configures whether a pullup device is activated on all associated port input pins. If a pin is used as output
this bit has no effect.
1 Pullup devices enabled
0 Pullup devices disabled
