INT 0D C - CPU-generated (80286+) - GENERAL PROTECTION VIOLATION Desc: the CPU(Central Processing Unit) The microprocessor which executes programs on your computer. generates this interrupt when it detects a protection violation which does not fit under any other category having a separate interrupt Notes: called in real mode when an instruction accesses a memory operand extending beyond offset FFFFh (i.e. WORD at FFFFh or DWORDDoubleword; four bytes. Commonly used to hold a 32-bit segment:offset or selector:offset address. at FFFDh or higher) in segment CS, DS, ES, FG, or GS a PUSH MEM or POP MEM instruction contains an invalid bit encoding in the second byte an instruction exceeds the maximum length allowed (10 bytes for 80286, 15 bytes for 80386/80486) an instruction wraps from offset FFFFh to offset 0000h called in protected mode on protection violations not covered by INT 06 through INT 0C, including segment limit violations write to read-only segments accesses using null DS or ES selectors accesses to segments with privilege greater than CPL wrong descriptor type called on 80486 protected-mode floating-point protection fault SeeAlso: INT 09"80486",INT 0C"STACK"
