Step 1: Initialize the quotient as a C register and clear it. Step 2: Initialize the memory pointer and load the second 8-bit number to the A register. Step 3: Move the 8-bit number to the B register. Step 4: Initialize the memory pointer and load the second 8-bit number to the A register. Step 5: Compare both numbers.
WebAll of the 8051 instructions are implemented, except for MOVX instructions, as the simulator does not handle external memory. JMP rel equates to either SJMP rel or AJMP rel. LJMP rel must be programmed explicitly. Similarly, CALL equates to ACALL. LCALL must be programmed explicitly. SET and EQU directives are implemented. ORG is implemented.
