Posted on July 06, 2005 at 17:16Port D is multiplexed with the ADC analog inputs. They may be driven by an arbritary analog value. If this is done, the P and N transistors of the inputs buffer may both saturate leading to a higher power consumption....

Posted on July 05, 2005 at 12:13Hi I am using an ST72F324 with analog inputs on port D When in power down mode, the input to these ports can be an arbritary value. This causes the digital input buffer to consume power - up to 200 microamps. Is there...
