HC05F6EM USER'S MANUAL
HC05EVS CONFIGURATION AND OPERATION
This chapter explains how to configure and use your F6EM as part of an
HC05EVS. For other parts of system installation or configuration, see
the HC05EVS operations manual. (If you will use your F6EM as part of
an MMDS05 system, go to Chapter 2 for corresponding information.)
Paragraph 3.1 explains how to set F6EM jumper headers. Paragraph 3.2
lists limitations on using the F6EM in an HC05EVS. Paragraph 3.3
explains pin assignments and signal descriptions for the logic analyzer
connector (P1). Paragraph 3.4 explains remaining system configuration.
Note that you can configure an F6EM already installed on the
HC05EVS platform board. To do so, disconnect platform-board power,
then follow the guidance of this chapter.
Be sure to disconnect power if you reconfigure an
installed EM. Reconfiguring EM jumper headers with
power left on can damage HC05EVS circuits.
Your F6EM has four jumper headers, P4, P6, P9 and P10. Paragraphs
3.1.1. through 3.1.4 explain how to configure these headers.
Jumper header P4 controls the path of a target reset. The diagram below
shows the factory configuration: the fabricated jumper between pins 1
and 2 enables your F6EM to reset the target when you press the user or
master reset switch.
