FSTSW memory location
Logic: [memory location] . status word
FSTSW stores the current value of the status word to a 16-bit memory
location. In the 80287 and 80387, you can store the status word directly
to the AX register of the 80x86 with the instruction FSTSW AX.

Note: If you use FSTSW instead of the no-wait FNSTSW form
and there is an outstanding unmasked exception,
deadlock results.
