3-482 Vol. 2A INT n/INTO/INT 3—Call to Interrupt Procedure
INSTRUCTION SET REFERENCE, A-M
Protected Mode Exceptions
#GP(0) If the instruction pointer in the IDT or in the interrupt-, trap-, or
task gate is beyond the code segment limits.
#GP(selector) If the segment selector in the interrupt-, trap-, or task gate is
NULL.
If an interrupt-, trap-, or task gate, code segment, or TSS
segment selector index is outside its descriptor table limits.
If the interrupt vector number is outside the IDT limits.
If an IDT descriptor is not an interrupt-, trap-, or task-descriptor.
If an interrupt is generated by the INT n, INT 3, or INTO instruc-
tion and the DPL of an interrupt-, trap-, or task-descriptor is less
than the CPL.
If the segment selector in an interrupt- or trap-gate does not
point to a segment descriptor for a code segment.
If the segment selector for a TSS has its local/global bit set for
local.
If a TSS segment descriptor specifies that the TSS is busy or not
available.
#SS(0) If pushing the return address, flags, or error code onto the stack
exceeds the bounds of the stack segment and no stack switch
occurs.
#SS(selector) If the SS register is being loaded and the segment pointed to is
marked not present.
If pushing the return address, flags, error code, or stack
segment pointer exceeds the bounds of the new stack segment
when a stack switch occurs.
#NP(selector) If code segment, interrupt-, trap-, or task gate, or TSS is not
present.
#TS(selector) If the RPL of the stack segment selector in the TSS is not equal
to the DPL of the code segment being accessed by the interrupt
or trap gate.
If DPL of the stack segment descriptor pointed to by the stack
segment selector in the TSS is not equal to the DPL of the code
segment descriptor for the interrupt or trap gate.
If the stack segment selector in the TSS is NULL.
If the stack segment for the TSS is not a writable data segment.
If segment-selector index for stack segment is outside
descriptor table limits.
#PF(fault-code) If a page fault occurs.
#UD If the LOCK prefix is used.
