TERMINOLOGY

This development module utilizes option select jumpers to configure default board operation. Terminology for application of the option jumpers is as follows:

Jumper – a plastic shunt that connects 2 terminals electrically 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 placed idle by installing on 1 pin so they will not be lost.

Cut-Trace – a circuit trace connection between component pads. The circuit trace may be cut using a knife to break the default connection. To reconnect the circuit, simply install a suitably sized 0-ohm resistor or attach a wire across the pads.

Signal names followed by an asterisk (*) denote active-low signals.

MEMORY MAP

Figure 1 below shows the device register memory map. Refer to the MC9S12XHY256 Reference Manual (RM) for further information.

SOFTWARE DEVELOPMENT

Software development requires the use of a compiler or an assembler supporting the HCS12(X) instruction set and a host PC operating a debug interface. CodeWarrior Development Studio is supplied with this board for application development and debug. Refer to the supporting CodeWarrior documentation for details on use and capabilities.

CAUTION:

When powered from the USB bus, do not exceed the 500mA maximum

allowable current drain. Damage to the target board or host PC may

result

NOTE:

10K ohm pull-ups are applied to BDM signals RESET* and BKGD

inside the P&E BDM block. These pull-ups are not shown on the

schematic.

DEVELOPMENT SUPPORT

Application development and debug for the target MC9S12XHY256 is supported through the background debug mode (BDM) interface. The BDM interface consists of an integrated USBMultilink BDM and a 6-pin interface header (BDM_PORT). The BDM_PORT header allows connecting an external HCS12 BDM cable. Refer to the MC9S12XHY Reference Manual for details and capabilities of the BDM.

Integrated BDM

The DEMO9S12XHY256 board features an integrated USB-BDM. The integrated BDM supports application development and debug via background debug mode. All necessary signals are provided by the integrated BDM. A USB, type B, connector provides connection from the target board to a host PC.

The integrated USB-Multilink BDM provides power and ground to the target board eliminating the need for external power. Power from the USB-Multilink BDM is derived from the USB bus; therefore, total current consumption for the target board, and connected circuitry, must not exceed 500mA. This current limit describes the current supplied by the USB cable to the BDM circuit, the target board, and any connected circuitry. Excessive current drain will violate the USB specification causing the bus to disconnect. Damage to the host PC USB hub or the target board may result.

BDM_PORT Header

An HCS(X)12 compatible BDM cable may be attached to the 6-pin BDM interface header (J2) if desired. Figure 2 below shows the pin-out for the BDM_PORT header.
