FNINIT      Initialize Coprocessor (No-wait)     Exception Flags: None

FNINIT

       Logic:      Initializes Coprocessor

     FNINIT is the no-wait form of FINIT. It performs a hardware reset of the
     coprocessor. FNINIT does not affect the synchronization between the 80x86
     and the 80x87.

     This instruction empties all stack elements and clears the exception
     flags.

        Note:          You should use this no-wait form of the instruction
                       only when there is a danger of generating an infinite
                       wait condition.
