TN.235.Coop with Coprocessor - The use of the 68881 or 68882 coprocessor is usually handled by the SANE package or by a development system’s libraries. Some developers may wish to use the coprocessor during special circumstances, such as at interrupt level or installing their own hardware floating point exception handlers. In these two situations, there are special requirements that must be met. These requirements will require floating–point assembly code and are discussed in this Technical Note. Changes since June 1989. Noted that the new Sound Manager no longer uses floating-point numbers at interrupt time.
