Segments
Taken Branch Debug Exception if PSR.tb is 1
If target offset in destination operand is beyond the new code
segment limit.
If the segment selector in the destination operand is null.
If the code segment selector in the gate is null.
If a memory operand effective address is outside the CS, DS, ES, FS,
or GS segment limit.
If the DS, ES, FS, or GS register is used to access memory and it
contains a null segment selector.
If code segment or gate or TSS selector index is outside descriptor
table limits.
If the segment descriptor pointed to by the segment selector in the
destination operand is not for a conforming-code segment,
nonconforming-code segment, call gate, task gate, or task state
segment.
If the DPL for a nonconforming-code segment is not equal to the CPL
or the RPL for the segment's segment selector is greater than the
CPL.
If the DPL for a conforming-code segment is greater than the CPL.
If the DPL from a call-gate, task-gate, or TSS segment descriptor is
less than the CPL or than the RPL of the call-gate, task-gate, or TSS's
segment selector.
If the segment descriptor for a segment selector from a call gate
does not indicate it is a code segment.
If the segment selector from a call gate is beyond the descriptor
table limits.
If the DPL for a code-segment obtained from a call gate is greater
than the CPL.
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.
