Development Support
A.4 Modular Development System (MMDS11)
The M68MMDS11 modular development system (MMDS11) is an emulator system for developing
embedded systems based on an M68HC11 microcontroller unit (MCU). The MMDS11 provides a bus
state analyzer (BSA) and real-time memory windows. The unit's integrated development environment
includes an editor, an assembler, user interface, and source-level debug. These features significantly
reduce the time necessary to develop and debug an embedded MCU system. The unit's compact size
requires a minimum of desk space.
The MMDS11 is one component of Freescale's modular approach to MCU-based product development.
This modular approach allows easy configuration of the MMDS11 to fit a wide range of requirements. It
also reduces development system cost by allowing the user to purchase only the modular components
necessary to support the particular MCU derivative.
MMDS11 features include:

Four data breakpoints (hardware breakpoints)
Hardware instruction breakpoints over either the 64-Kbyte M68HC11 memory map or over a
1-Mbyte bank switched memory map
32 real-time variables, nine of which can be displayed in the variables window. These variables
may be read or written while the MCU is running
32 bytes of real-time memory can be displayed in the memory window. This memory may be read
or written while the MCU is running
64 Kbytes of fast emulation memory (SRAM)
Current-limited target input/output connections
Six software-selectable oscillator clock sources: five internally generated frequencies and an
external frequency via a bus analyzer logic clip
Command and response logging to MS-DOS
SCRIPT command for automatic execution of a sequence of MMDS11 commands
Assembly or C-language source-level debugging with global variable viewing
Host/emulator communications speeds as high as 57,600 baud for quick program loading
8 K x 64 real-time trace buffer
Display of real-time trace data as raw data, disassembled instructions, raw data and
disassembled instructions, or assembly-language source code
Four hardware triggers for commencing trace and to provide breakpoints
Nine triggering modes
As many as 8190 pre- or post-trigger points for trace data
16 general-purpose logic clips, four of which can be used to trigger the bus state analyzer
sequencer
16-bit time tag or an optional 24-bit time tag that reduces the logic clips traced from 16 to eight
