INSTRUCTION SET REFERENCE, N-Z
Numeric Exceptions
None.
Protected Mode Exceptions
#GP(0) If a memory operand effective address is outside the CS, DS,
ES, FS, or GS segment limit.
If a memory operand is not aligned on a 16-byte boundary,
regardless of segment.
#SS(0) If a memory operand effective address is outside the SS
segment limit.
#UD If CR0.EM[bit 2] = 1.
If CR4.OSFXSR[bit 9] = 0.
If CPUID.01H:EDX.SSE2[bit 26] = 0.
#NM If CR0.TS[bit 3] = 1.
#PF(fault-code) If a page fault occurs.
Real-Address Mode Exceptions
#GP(0) If a memory operand is not aligned on a 16-byte boundary,
regardless of segment.
If any part of the operand lies outside of the effective address
space from 0 to FFFFH.
#UD If CR0.EM[bit 2] = 1.
If CR4.OSFXSR[bit 9] = 0.
If CPUID.01H:EDX.SSE2[bit 26] = 0.
#NM If CR0.TS[bit 3] = 1.
Virtual-8086 Mode Exceptions
Same exceptions as in Real Address Mode
#PF(fault-code) For a page fault.
Compatibility Mode Exceptions
Same as for protected mode exceptions.
64-Bit Mode Exceptions
#SS(0) If a memory address referencing the SS segment is in a non-
canonical form.
#GP(0) If the memory address is in a non-canonical form.
If memory operand is not aligned on a 16-byte boundary,
regardless of segment.
