标题: 怎么快速的送较大量的数据到RAM？
比如我有数据
DB 00H,00H,00H,00H,00H,00H,00H,0FEH,40H,40H,40H,40H,40H,00H,00H,00H
DB 00H,40H,40H,40H,40H,40H,40H,7FH,40H,40H,40H,40H,40H,60H,40H,00H,
怎么把这些数据读进RAM的30H-4FH??

用间址方式
TABLE
……
      DB  00H,00H,00H,00H,00H,00H,00H,0FEH,40H,40H,40H,40H,40H,00H,00H,00H
      DB  00H,40H,40H,40H,40H,40H,40H,7FH,40H,40H,40H,40H,40H,60H,40H,00H,
……

      MOVLW 30H
      MOVWF FSR
LOOP
      CALL    TABLE
      MOVWF INDF
      INCF    FSR
      MOVLW 50H
      XORWF    FSR，W
      BTFSS    STATUS，Z
      GOTO       LOOP
      ……
