Section 3. Preparation and Operation
3.1 Introduction
This section explains DEMO9S12NE64 preparation: how to set switches and
how to make system connections.
CAUTION: ESD
Protection
Freescale development tools contain static-sensitive components. These
boards are subject to damage from electrostatic discharge (ESD). To prevent
such damage, you must use static-safe work surfaces and grounding straps, as
defined in ANSI/EOS/ESD S6.1 and ANSI/EOS/ESD S4.1. All handling of these
boards must be in accordance with ANSI/EAI 625.
3.2 Configuring Board Components
3.3 Running the Automated Board Test
This section explains how to test the DEMO9S12NE64 using test software
located on the included documentation CD-ROM. This test will allow you to
verify the proper operation of your board.
Table 3-1 Configuration Components
Component Position Effect
Switch, SW3 SW3: Controls the value of I/O pin PG<4>. In the 1 position
(labeled in silk on the case) PG<4> is pulled high to 3.3 VDC
through a 10K ohm resistor. In the 0 position, PG<4> is tied
directly to GND.
This switch is used by the serial monitor to put the monitor into
Load or Run mode. To put the monitor into Load mode, set SW3 to
the 0 position. To put the monitor into Run mode, set SW3 to the 1
position.
