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: Freescale Semiconductor, Inc... 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.

Chapter 2 Technical Summary Freescale Semiconductor, Inc... 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. Table 2-1.

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. GND +3.3V DC +5V DC +9V DC Figure 2-1.

It uses a simple 2-wire asynchronous serial interface and is translated to RS-232 signaling levels. 1,4,6 connected (host null) 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 Motorola OnCE development port. This connector allows the connection of a OnCE-style background debug cable for software development, programming and debugging in real time.
