大概是在每一顆具有AD功能PICmicro的data sheet中都有寫吧：
1. Analog levels on a digitally configured iput will be accurately converted. 2. Analog levels on any pin defined as a digital input may cause the digital input buffer to consume current out of the device's specification limits. 所以，看來應該只是耗電較高而已！ 心情好一點了吧！

使用18F452做AD轉換，用了AN2通道，卻不小心將AN2在ADCON1中設置成D，結果因爲不影響AD精度，測試時並未發現這個錯誤，産品已經賣出千台，不知會有什麽後果？誰能告知，鬱悶之至。
