我要將2個8bit暫存器A、B相乘，
將16bit結果分別存於2個8bit暫存器MuxHigh與MuxLow中 以下是我的程式： ============================================== MuxAB clrf MuxHigh ; clrw Loop addwf A,W btfsc STATUS,C incf MuxHigh,F decfsz B,F goto Loop movwf MuxLow return ======================================= 我想要累加A暫存器，共累加B次 (1)而我的A=1.8472 B=0.8765 那我的A與B該怎麼宣告 是不是要將A.B值 先畫成010101...的形式 (2)最後若我想要在portC作輸出 該怎麼設定啊 PS:我是用PIC16F877晶片.. 麻煩一下～～ 謝...
