Examples:
Given: Register 00H = 4FH, register 01H = 02H, and register 02H = 5EH:
CLR 00H
→
Register 00H = 00H
CLR @01H
→
Register 01H = 02H, register 02H = 00H
In Register (R) addressing mode, the statement "CLR 00H" clears the destination register 00H
value to 00H. In the second example, the statement "CLR @01H" uses Indirect Register (IR)
addressing mode to clear the 02H register value to 00H.
