WebINT SOFTWARE INTERRUPT. The INT instruction generates a software interrupt. This is handled in the same way as a hardware interrupt, described earlier. A software interrupt is similar to a far CALL instruction, except that the flags are also pushed onto the stack before CS and IP are pushed (and the TF and IF flags are cleared). WebNo instructions that use the stack can be used until the stack-segment register (SS) has been loaded. SS must point to an area in RAM. 10.2.2 Interrupt Table The initial state of the 80386 leaves interrupts disabled; however, the processor will still attempt to access the interrupt table if an exception or nonmaskable interrupt (NMI) occurs. fischron terrariaWebRISC-V (pronounced "risk-five",: 1 ) is an open standard instruction set architecture (ISA) based on established reduced instruction set computer (RISC) principles.
