CPU-generated (80286,80386) - PROCESSOR EXTENSION PROTECTION ERROR

Desc: Called if the coprocessor attempts to access memory outside a segment boundary; it may occur at an arbitrary time after the coprocessor instruction was issued

Notes: Until the condition is cleared or the coprocessor is reset, the only coprocessor instruction which may be used is FNINIT; WAIT or other coprocessor instructions will cause a deadlock because the coprocessor is still busy waiting for data. For the 486+, a coprocessor protection error generates an INT 0D
