#94801 - static current? Responding to: ???'s previous message |
I don't think you can blame the pullups for that; if you set the port bit to 1, there is nothing which would draw the current through them; if you set it to 0, it turns off thanks to the built-in feedback.
I don't know what causes the high static current. The oscillator circuit may be one suspect, as it is somewhat "analog", but I don't believe it is as much as several mA, so we need somebody who knows the guts of the chip better. Jan Waclawek |
