7. Floating-Point Exceptions
7.2 Exception Trap Processing
When a floating-point exception trap is taken, the Cause register indicates the floating-point coprocessor is the cause of the exception trap. The Floating-Point Exception (FPE) code is used, and the Cause bits of the floating-point Control/Status register indicate the reason for the floating-point exception. These bits are, in effect, an extension of the system coprocessor Cause register.
