M68060 USER’S MANUAL
The MC68LC060 is a derivative of the MC68060. The MC68LC060 has the same execution
unit and MMU as the MC68060, but has no FPU. The MC68LC060 is 100% pin compatible
with the MC68060. Disregard all information concerning the FPU when reading this manual.
The following difference exists between the MC68LC060 and the MC68060:

countered, a floating-point disabled exception is taken.

fying the device as an MC68LC/EC060.
