"但當RA0的輸入訊號為LOW的時後,C2Vout為什麼也會變為1? "

看了問題在查data sheet我也一樣不懂為什麼會這樣,Bank 有沒有切對?

Dear All,

請問當我選擇使用1組獨立的比較器時是否只有C2Vout會有作用?我的設定如下:
CMCON: 0b00000101 (one independent comparator)
general IO pin(RA0:input,RA3:output)
comparator pin(RA1:5V input,RA2:4.0V Vref input)

當RA1的電壓 < RA2的電壓時,C2Vout會變為1(正確)
但當RA0的輸入訊號為LOW的時後,C2Vout為什麼也會變為1?

請問為什麼會有這樣的動作,不是應該只有1組比較器會動作嗎?

麻煩各位先進能提供我一些意見,謝謝!!
