Port V pull device enable—Enable pull devices on input pins
These bits configure whether a pull device is activated, if the associated pin is used as an input. This bit has no effect
if the pin is used as an output. Out of reset no pull device is enabled.
1 Pull device enabled.
0 Pull device disabled.
Port V pull device select—Determine pull device polarity on input pins
This register serves a dual purpose by selecting the polarity of the active interrupt edge as well as selecting a pull-up
or pull-down device if enabled.
1 A pull-down device is connected to the associated Port V pin, if enabled by the associated bit in register PERV and
0 A pull-up device is connected to the associated Port V pin, if enabled by the associated bit in register PERV and if
