Cautionary Notes
1. Electrostatic Discharge (ESD) prevention measures should be applied whenever
handling this product. ESD damage is not a warranty repair item.
2. EMC Information on the 56F800 Demonstration Board:
a. This product as shipped from the factory with associated power supplies and
cables, has been tested and meets with requirements of CE and the FCC as a
CLASS A product.
b. This product is designed and intended for use as a development platform for
hardware or software in an educational or professional laboratory.
c. In a domestic environment this product may cause radio interference in which
case the user may be required to take adequate prevention measures.
d. Attaching additional wiring to this product or modifying the products operation
from the factory default as shipped may effect its performance and also cause
interference with other apparatus in the immediate vicinity. If such interference
is detected, suitable mitigating measures should be taken.
Terminology
This development board applies option selection jumpers. Terminology for application of
the option jumpers is as follows:
Jumper on, in, or installed = jumper is a plastic shunt that fits across 2 pins and the shunt is
installed so that the 2 pins are connected with the shunt.
Jumper off, out, or idle = jumper or shunt is installed so that only 1 pin holds the shunt, no
2 pins are connected, or jumper is removed. It is recommended that the jumpers be idled
by installing on 1 pin so they will not be lost.
This development board applies CUT_AWAY option selections. These option selections
apply surface mount resistor locations with a printed circuit board trace connecting both
component pads. This type connection places an equivalent 0-ohm type resistor in series
with the I/O signal and the user component or I/O connector on the board. These
connections maybe cut with a razor blade or similar type knife between the component
pads to isolate the default connection provided. Reconnection of the cut-away type pads
can be made by either installing a 0 ohm 0805 size surface mount resistor or a small wire
jumper on the component pads.

Technical Summary
This chapter describes the 56F800 Demonstration Board’s available options.
2.1 OPTIONS
2.1.1 HOST_ENABLE
The HOST_ENABLE option jumper is installed by default and enables the Host JTAG
interface on the board. With the option jumper installed, the 56F801 device will reset into
Debug mode and await Host commands on the Host JTAG port (P1). Removing the
HOST_ENABLE option jumper will allow the 56F801 device to reset normally and
execute program code contained in the device’s Flash memory.
•HOST_ENABLE = INSTALLED: Debug Mode; host JTAG port is active
•HOST_ENABLE = OPEN or IDLE: Normal Mode; executes user code in Flash
2.1.2 CUT_AWAY Options
CUT_AWAY options allow the user to disconnect dedicated 56F801 I/O port resources
from development board connectors or peripherals. The CUT_AWAY options also allow
for re-establishing the connection by installing surface-mount 0805-size 0 ohm resistors or
mod wire with the use of a soldering iron. Normal operation of the 56F800 Demonstration
Board generally does not require any manipulation of the CUT_AWAY options.

2.2 PORTS AND CONNECTORS
2.2.1 PWR Jack
This connector provides power input to the board by default. The PWR jack accepts a
standard 2.0 ~ 2.1mm center-barrel plug connector (positive voltage center) to provide the
+VIN supply of +9V DC at 200ma.
2.2.2 POWER PORT
Provides access to the +9V DC input, GND (power ground), +5V DC and +3.3V DC
power supplies. The +9V DC input should only be applied by PWR jack or Power Port,
but not both, or a supply conflict may occur and the 56F800 Demonstration Board could
be damaged. Power Port accepts a 3.5mm pin space terminal block.

2.2.6 COM1
RTS and CTS flow control connection pads are provided on the 56F800 Demonstration Board to
apply unassigned 56F801 I/O to support flow control on COM1. The RTS pad provides RS-232
level output conversion to COM1 port pin 8. The CTS pad provides RS-232-converted input
from COM1 pin 7.
The 1, 4, 6, and 9 pins provide RS-232 status. The 1, 4, and 6 pins are connected on the bottom
of the development board to provide NULL status to the host. The user may isolate pins and
provide the status connections to the host by applying I/O signals and RS-232 level conversion.

2.2.7 JTAG / OnCE
The JTAG 14-pin connector is compatible with the Freescale OnCE development port. This
connector allows the connection of a OnCE-style background debug cable for software
development, programming and debugging in real time.
Note: HOST_ENABLE option must be open or idle to apply this connector.
2.2.8 P1 - HOST JTAG
The P1 - Host JTAG connector provides development port interface to a hosting Personal
Computer’s LPT or Printer port. The HOST_ENABLE option jumper must be installed for this
port to operate.
Note: HOST_ENABLE option must be installed to apply this connector.
