Instruction types. ? Arithmetic operations. ? Logical operations. ? Data transfer instructions. ? Boolean variable instructions. ? Program branching instructions. In this lecture we will look at the various addressing modes and the instructions. The 8051. Architecture course would be helpful in understanding some of the
Alphabetical List of Instructions. ACALL - Absolute Call; ADD, ADDC - Add Accumulator (With Carry); AJMP - Absolute Jump; ANL - Bitwise AND; CJNE - Compare and Jump if Not Equal; CLR - Clear Register; CPL - Complement Register; DA - Decimal Adjust; DEC - Decrement Register; DIV - Divide Accumulator by B
2 Jan 2010 JUMP SJMP
- The 8051 provides four different types of unconditional jump instructions:
- Short Jump – SJMP addr
- Uses an 8-bit signed offset relative to the 1 st byte of the next instruction .
- the range of destination
Module 2 : Intel 8051 Microcontroller. Lecture 10 : Program Branching Instructions Jump that replaces the PC (program counter) content with a new address that is greater than (the address following the jump instruction by 127 or less) or less than (the address following the jump by 128 or less) is called a relative jump.
8 Jul 2013 Conditional jump instructions: a jump to a new program location is executed only if a specified condition is met. Otherwise, the program normally proceeds with the next instruction. ACALL addr11 - Absolute subroutine call. addr11: Subroutine address. Description: Instruction unconditionally calls a
Saving PC on stack before Branch instruction- call routine at new value of Program Counter. (PC). Before call - (1) Increment SP and then move the next instruction PCL byte to. SP pointed address (2) Increment SP and then move the next instruction PCH byte to SP pointed address. Execution of Subroutine Call Instructions
Branch instructions. Unconditional Branch Instructions. Operation: AJMP. Description: AJMP unconditionally jumps to the indicated code address. The new value for the Program Counter is calculated by replacing the least-significant-byte of the. Program Counter with the second byte of the AJMP instruction, and replacing

The first part of each instruction, called MNEMONIC refers to the operation an instruction performs (copy, addition, logic operation etc.). Mnemonics are
8051 Conditional Jump Instructions. Conditional Jump Example. Conditional Jump Example. Unconditional Jump Instructions. All conditional jumps are short jumps. Target address within -128 to +127 of PC. LJMP (long jump): 3-byte instruction. 2-byte target address: 0000 to FFFFH; Original 8051 has only 4KB on-chip
Conditional jumps for the 8051 are summarized in Table 3-1. More details of each instruction are provided in Appendix A. In Table 3-1, notice that some of the instructions, such as JZ (jump if A = zero) and JC (jump if carry), jump only if a certain condition is met. Next we examine some conditional jump instructions with
