Port 5 Digital Input Control
Port 5 pins may be used for either digital or analog input. By setting the respective bit in
register P5DIDIS, the digital input stage of the respective Port 5 pin can be disconnected
from the pin. This is recommended when the pin is to be used as analog input as it
reduces the current through the digital input stage and prevents it from toggling while the
(analog) input level is between the digital low and high thresholds. Thus, the consumed
power and the generated noise can be reduced.
After reset all digital input stages are enabled.
