MC68HC11G5
This section discusses the M68HC11 central processing unit (CPU) architecture, its addressing
modes and the instruction set (by instruction type). Everything discussed in this section applies to
the MC68HC11G5. For more detailed information on the instruction set, refer to the M68HC11
Reference Manual (M68HC11RM/D).
In addition to being able to execute all M6800 and M6801 instructions, the MC68HC11G5 uses a
4-page opcode map to allow execution of 91 new opcodes (see 12.3: INSTRUCTION SET).
Seven registers, shown in Figure 12-1 and discussed in the following paragraphs, are available
to programmers.
