With the exception of the floating-point unit (FPU) and its registers, the MC68LC040 pro-
gramming model, data formats and types, instruction set (except all instructions beginning
with an “F”), caches, and MMUs are the same as those described in Section 1 Introduction
for the MC68040. Figures A-2 and A-3 illustrate the programming model and functional sig-
nal groups for the MC68LC040.
