Pull-up Port K Enable—Enable pull-up devices on all Port K input pins
This bit configures whether pull-up devices are activated, if the pins are used as inputs. This bit has no effect if the
pins are used as outputs. Out of reset the pull-up devices are enabled.
1 Pull-up devices enabled.
0 Pull-up devices disabled.
BKGD pin pull-up Enable—Enable pull-up devices on BKGD pin
This bit configures whether a pull-up device is activated, if the pin is used as input. This bit has no effect if the pin is
used as outputs. Out of reset the pull-up device is enabled.
1 Pull-up device enabled.
0 Pull-up device disabled.
Reserved—
Pull-up Port E Enable—Enable pull-up devices on all Port E input pins except on pins 5 and 6 which have pull-down
devices only enabled during reset. This bit has no effect on these pins.
This bit configures whether pull-up devices are activated, if the pins are used as inputs. This bit has no effect if the
pins are used as outputs. Out of reset the pull-up devices are enabled.
