3.3 CPU Registers
Technical Data

This section presents information on M68HC11:
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.
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
