 Although the CPU now fits into a feature chart more like the Motorola 68030, it continues to include the 68040's caches and pipeline and is thus significantly faster than the 68030.Some mask revisions of the 68LC040 contained a bug that prevents the chip from operating correctly when a software FPU emulator is used.According to Motorola's errata, any chip with a mask set 2E71M or later does not contain the bug.
