USER’S MANUAL
This section is an overview of the central processor unit (CPU16). For detailed infor-
mation, refer to the CPU16 Reference Manual (CPU16RM/AD).
The CPU16 provides compatibility with the M68HC11 CPU and also provides addition-
al capabilities associated with 16- and 32-bit data sizes, 20-bit addressing, and digital
signal processing. CPU16 registers are an integral part of the CPU and are not ad-
dressed as memory locations.
The CPU16 treats all peripheral, I/O, and memory locations as parts of a linear 1
Megabyte address space. There are no special instructions for I/O that are separate
from instructions for addressing memory. Address space is made up of sixteen 64-
Kbyte banks. Specialized bank addressing techniques and support registers provide
transparent access across bank boundaries.
The CPU16 interacts with external devices and with other modules within the micro-
controller via a standardized bus and bus interface. There are bus protocols used for
memory and peripheral accesses, as well as for managing a hierarchy of interrupt
priorities.
Figure 4-1 shows the CPU16 register model. Refer to the paragraphs that follow for a
detailed description of each register.
