CHAPTER 3

HC05EVS CONFIGURATION AND OPERATION

This chapter explains how to configure your P3EM 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 P3EM as part of an MMDS05 system, go to Chapter
2 for configuration information.)

Paragraph 3.1 explains how to set P3EM jumper headers. Paragraph 3.2 explains
considerations pertaining to the MCU you emulate. Paragraph 3.3 lists limitations on using the
P3EM 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 P3EM 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 P3EM JUMPER HEADERS

Your P3EM has four jumper headers, J1 through J4. Paragraphs 3.1.1. through 3.1.3 explain
how to configure these headers.
