Emulation Module

MICROCONTROLLER EMULATION MODULE FOR THE FSICE, MMDS, or MMEVS

Device specific Emulation Modules (EMs) complete the functionality of the sophisticated NXP^® Modular Development System (MMDS), the economical NXP Modular Evaluation System (MMEVS), or NXP In-circuit emulator (FSICE). The EM board contains circuitry that emulates the specific features of the target HC(9)08 microcontroller.

The EM attaches to either development system (MMDS, MMEVS, or FSICE) through two expansion connectors located on the bottom side of the EM board. Connection to your target system is then made through a separately purchased target cable and target head adapter that attaches to a target connector located on the top side of the EM board. In addition to the target connector, each EM includes a connector which provides the ability to interface the EM to a logic analyzer for external hardware trace of code execution.

Limitations listed here apply to using your EML08AP emulator, as opposed to using the actual MCU in your target system:

Limitation 1 - Continuous Autoscan Mode in ADC module:
The emulator may not be able to obtain correct ADC conversion value on ADC channel ATD0 to ATD3 if the ADC module is configured in continuous autoscan mode.

Limitation 2 - Low voltage inhibit interrupt in LVI module:
The emulator can not emulate the LVI interrupt in AP64/AP64A LVI module.

Limitation 3 - Frequency Limitation below nominal supply voltages at 5V
Every effort has been made in the design of the EML08AP emulator to provide emulation over the full frequency range of the MCU however limitations exist at the high end of the frequency range.

The emulator module will likely not be able to operate at the 32MHz clock frequency as specified for the MCU at a supply voltage of 5V. The common symptom is unreliable memory accesses. Since the program is in memory a typical manifestation of the symptom is an inability to load code or data or to execute code.
