Guys, I made this code in asm for a PIC 16F877 that decreases Value (high and low) to 0x00 and increases to 0x64. Does anyone see something wrong with this code, or do you think it could be improved?
DEC MOVF VALUE_HIGH,W SUBLW B'00000000' BTFSS STATUS,C GOTO DC_DEC MOVF VALUE_LOW,W SUBLW B'00000000' BTFSC STATUS,C GOTO EXIT DC_DEC DECF VALUE_LOW,F MOVLW .255 XORWF VALUE_LOW,W BTFSC STATUS,Z DECF VALUE_HIGH,F GOTO EXIT INC MOVLW B'00000011' SUBWF VALUE_HIGH,W BTFSS STATUS,C GOTO DC_INC MOVLW B'11101000' SUBWF VALUE_LOW,W BTFSC STATUS,C GOTO EXIT DC_INC INCF VALUE_LOW,F BTFSC STATUS,Z INCF VALUE_HIGH,F GOTO EXIT
