Central Processor Unit (CPU)
4.1 Introduction
Features of the M68HC11 Family include:
The CPU is designed to treat all peripheral, input/output (I/O), and memory locations identically as
addresses in the 64-Kbyte memory map. This is referred to as memory-mapped I/O. There are no special
instructions for I/O that are separate from those used for memory. This architecture also allows accessing
an operand from an external memory location with no execution time penalty.
4.2 CPU Registers
M68HC11 CPU registers are an integral part of the CPU and are not addressed as if they were memory
locations. The seven registers, discussed in the following paragraphs, are shown in
