This instruction copies a word from two memory locations into the register specified in the instruction. It then copies a word from the next two memory locations into the DS (ES) register. It is useful for pointing to SI (DI) and DS (ES) at the start of a string before using a string instruction. Usage LDS dest, src. WebThe IRET instruction is used at the end of the interrupt service routine to return execution to the interrupted program.

WebVME mode (virtual-8086 mode extensions): CR0.PE = 1, EFLAGS.VM = 1, and CR4.VME = 1. If IOPL &lt; 3, EFLAGS.VIP = 1, and either VME mode or PVI mode is active, STI sets the VIF flag in the EFLAGS register, leaving IF unaffected. Table 4-24 indicates the action of the STI instruction depending on the processor operating mode, IOPL, CPL, and EFLAGS.VIP.
