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?
