A.1 MC68LC040 DIFFERENCES
The following differences exist between the MC68LC040 and MC68040:
A-4
MC68LC040
• The MC68LC040 does not implement the small output bufferr impedance selection
• The DLE pin name has been changed to JS0
• The MC68LC040 does not implement the data latch (DLE) or multiplexed bus modes
• The MC68LC040 does not contain an FPU, which causes unimplemented floating-point
mode.
of operation. All timing and drive capabilities of the MC68LC040 are equivalent to those
of the MC68040 in small output buffer impedance mode.
exceptions to occur using a new eight-word stack frame format.
