CHAPTER 3

HC05EVS CONFIGURATION AND OPERATION

This chapter explains how to configure your D32EM 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 D32EM as part of an MMDS05 system, go to
Chapter 2 for configuration information.)

Paragraph 3.1 explains how to set D32EM jumper headers. Paragraph 3.2 explains
considerations pertaining to the MCU you emulate. Paragraph 3.3 lists limitations on using
the D32EM 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 D32EM 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 D32EM JUMPER HEADERS

Your D32EM has four jumper headers, J1 through J4 and two switch arrays S1 and S2.
Paragraphs 3.1.1. through 3.1.4 explain how to configure these headers and switches.
