A.5 Motorola Modular Development System (MMDS11)
M68HC11E Family — Rev. 3.2
MOTOROLA
The M68MMDS11 Motorola 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 Motorola’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:
•
•
•
Real-time, non-intrusive, in-circuit emulation at the MCU’s
operating frequency
Real-time bus state analyzer
– 8 K x 64 real-time trace buffer
– Display of real-time trace data as raw data, disassembled
– Four hardware triggers for commencing trace and to provide
– 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
– 16-bit time tag or an optional 24-bit time tag that reduces the
