Analog On Digital Port

Question asked by Mike NN on Jan 3, 2018

On LPC11E14 I use PIO0_12 and PIO0_14 as encoder inputs.  As such these are both configured as digital inputs.  I would like to add broken cable detection, which would involve placing an analog voltage (VCC/2) on PIO0_12 and PIO0_14.  Then these pins would also connect to an analog input simultaneously.  Are there any consequences to placing the VCC/2 level on the digitally configured inputs?  Higher current drain perhaps?  Latch up?
