Splet8051 / 8052 Microcontroller Instruction Set DEC - Decrement Register Description: DEC decrements the value of register by 1. If the initial value of register is 0, decrementing the value will cause it to reset to 255 (0xFF Hex). Note: The Carry Flag is NOT set when the value "rolls over" from 0 to 255. See Also: INC, SUBB, Instruction Set SpletRLC instruction in 8051 -> Make a circular left shift with carry flag. MSB goes to carry flag and carry flag comes in LSB and rest of bits get shifted to left by 1 place. Lets take an example. A<=B00000001 : decimal equivalent =1 RLC A A will be B00000010 : decimal equivalent=2 We have assumed that carry flag is 0.
