6.2 Introduction
This section describes the central processor unit (CPU08, Version A).
The M68HC08 CPU is an enhanced and fully object-code-compatible
version of the M68HC05 CPU. The CPU08 Reference Manual
(Freescale document number CPU08RM/AD) contains a description of
the CPU instruction set, addressing modes, and architecture.
