CHAPTER 3
HC05EVS CONFIGURATION AND OPERATION
This chapter explains how to configure your E24EM for use as part of an HC05EVS. For
other parts of system installation or configuration, see the HC05EVS operations manual
(HC05EVSOM/D). (If you will use your E24EM as part of an MMDS05 system, go to
Chapter 2 for configuration information.)
Paragraph 3.1 explains how to set E24EM jumper headers. Paragraph 3.2 explains
considerations pertaining to the MCU you emulate. Paragraph 3.3 lists limitations on using the
E24EM in an HC05EVS. Paragraph 3.4 explains pin assignments and signal descriptions for
the logic analyzer connector (P1). Paragraph 3.5 explains remaining system configuration.
Note that you can configure a E24EM already installed on the HC05EVS platform board. To
do so, disconnect platform-board power, then follow the guidance of this chapter.
CAUTION
Be sure to disconnect power if you reconfigure an installed EM. Reconfiguring
EM jumper headers with power left on can damage HC05EVS circuits.
3.1 SETTING E24EM JUMPER HEADERS
Your E24EM has four jumper headers, J1 to J4. Sections 3.1 explain how to configure these
headers.
