This section explains DEMO9S12NE64 preparation, how to set switches and
how to make system connections. It also consists of connector pin
assignments, connector signal descriptions, and other information that may be
useful in your development activities.
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.
Connector J50 is an I/O expansion connector that can be used to interface the
DEMO9S12NE64 to other boards. Figure 2-1 and Table 2-2 give the pin
assignments and signal descriptions for connector J50.

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.
