FPU Exception Flag Field
Each time an FPU operation instruction is executed,
the FPU exception cause field is cleared to 0. When an
FPU exception occurs, the bits corresponding to FPU
exception cause field and flag field are set to 1. The
FPU exception flag field remains set to 1 until it is
cleared to 0 by software.
For bit allocations of each field, see table 2.2.
