4.5 Operating Modes
4.5.1 Single-Chip Mode
4.5.2 Expanded Mode
M68HC11K Family
MOTOROLA
The two normal modes of operation in the M68HC11K Family are:
The two special modes of operation are:
The logic levels applied at reset to input pins MODA and MODB
determine the operating mode. See
In single-chip mode, the MCU functions as a self-contained
microcontroller. In this mode, all address and data activity occurs within
the MCU. Ports B, C, F, G, and H are available for general-purpose I/O
because the external address and data buses are not required.
In expanded mode, the MCU uses ports B, C, F, and G to access a
64-Kbyte address space. This includes:

For More Information On This Product,
Single-chip mode — All port pins available for input/output (I/O);
only on-board memory accessible
Expanded mode — Access to internal and external memory; 25
I/O pins used for interface
Bootstrap mode — A variation of single-chip mode; executes a
bootloader program in an internal bootstrap read-only memory
(ROM)
Test mode — A variation of the expanded mode used in
production testing; allows privileged access to internal resources
