INSTRUCTION SET DESCRIPTIONS Table C-4. Instruction Set (Continued) Name Description Operation Flags Affected OUTS POP NOTE: Out String: OUTS port, src_string Performs block output from memory to an I/O port. The port address is placed in the DX register. The memory address is placed in the SI register. This instruction uses the DS segment register, but this may be changed with a segment override instruction. After the data transfer takes place, the pointer register (SI) increments or decrements, depending on the value of the direction flag (DF). The pointer register changes by 1 for byte transfers or 2 for word transfers. Instruction Operands: OUTS port, src_string OUTS (repeat) port, src_string Pop: POP dest Transfers the word at the current top of stack (pointed to by SP) to the destination operand and then increments SP by two to point to the new top of stack. Instruction Operands: POP reg POP seg-reg (CS illegal) POP mem (dst) ← (src) AF – CF – DF – IF – OF – PF – SF – TF – ZF – (dest) ← ((SP) + 1:(SP)) (SP) ← (SP) + 2 The three symbols used in the Flags Affected column are defined as follows: – the contents of the flag remain unchanged after the instruction is executed the contents of the flag is undefined after the instruction is executed üthe flag is updated after the instruction is executed AF – CF – DF – IF – OF – PF – SF – TF – ZF – C-33
INSTRUCTION SET DESCRIPTIONS Table C-4. Instruction Set (Continued) Name Description Operation Flags Affected POPA POPF PUSH NOTE: Pop All: POPA Pops all data, pointer, and index registers off of the stack. The SP value popped is discarded. Instruction Operands: none Pop Flags: POPF Transfers specific bits from the word at the current top of stack (pointed to by register SP) into the 8086/8088 flags, replacing whatever values the flags previously contained. SP is then incremented by two to point to the new top of stack. Instruction Operands: none Push: PUSH src Decrements SP by two and then transfers a word from the source operand to the top of stack now pointed to by SP. Instruction Operands: PUSH reg PUSH seg-reg (CS legal) PUSH mem (DI) ← ((SP) + 1:(SP)) (SP) ← (SP) + 2 (SI) ← ((SP) + 1:(SP)) (SP) ← (SP) + 2 (BP) ← ((SP) + 1:(SP)) (SP) ← (SP) + 2 (BX) ← ((SP) + 1:(SP)) (SP) ← (SP) + 2 (DX) ← ((SP) + 1:(SP)) (SP) ← (SP) + 2 (CX) ← ((SP) + 1:(SP)) (SP) ← (SP) + 2 (AX) ← ((SP) + 1:(SP)) (SP) ← (SP) + 2 Flags ← ((SP) + 1:(SP)) (SP) ← (SP) + 2 (SP) ← (SP) – 2 ((SP) + 1:(SP)) ← (src) The three symbols used in the Flags Affected column are defined as follows: – the contents of the flag remain unchanged after the instruction is executed the contents of the flag is undefined after the instruction is executed üthe flag is updated after the instruction is executed AF – CF – DF – IF – OF – PF – SF – TF – ZF – AF ü CF ü DF ü IF ü OF ü PF ü SF ü TF ü ZF ü AF – CF – DF – IF – OF – PF – SF – TF – ZF – C-34
