4. EDK O PERA TION 4.1. USER INTERFACE The EDK provides two buttons for influencing the operation of the board. The purpose of each b utton is clearly marked next to it.
4.2.2. C RYSTAL C HOICE The operating crystal frequency has been chosen to support the fa stest operation with the fastest serial operating speeds. The value of the crystal is 18.432MHz. The following table shows the baud rates and Baud Rate Register (BRR) setting required for each communication rate using the above default operating speed.
4.4. I2C EEPROM The board has been tested with an Atmel AT24C04AN- 10SI-2.7 I2C EEPROM device (Not supplied). The device is configured to connect to dedicated I2C pins on Ports P56 and P57. 4.5. LIN I NTERFACE The board has been tested with an Philips TJA1020TD device (Not supplied).
5. B OARD O PTIONS The EDK has a number of configuration settings set by four jumpers CJ4 (A, B, C, D) and zero-ohm links. Common EDK functions can be set using the jumpers as de scribed in sect ions 5.2. The additional zero-ohm links provid e additional features that may be required to interface with other systems.
5.2. EDK O PTIONS – CJ4 The EDK options provide access to co mmonly used features of the EDK range. These jumpers must be fitted at all times to ensure correct operation of the EDK.
5.3. O PTION L INK S ELECTION The following sections show the option links that apply to each pe ripheral device. The tables all use the same key of symbols which is given below: X – Groups of options one set of which must be fitted for correct operation of the EDK.
5.3.3. SPI – S ERIAL P ERIPHERAL I NTERFACE The SPI interface is not directly compatible with the SCI in terface on the device. Selection of the connections to the SPI interface should therefore be chosen to allow t he operation of other peripherals as required.
6. M ICROCONTROLLER H E ADER C ONNECTIONS The following table lists the connections to each or the headers on the board. 6.1. H EADER J1 J1 Pin No Function EDK Sy mbol Device pin Pin No Function EDK S.
7. C ODE D EVELOPMENT 7.1. HMON 7.1.1. M ODE S UPPORT The HMON library is built to support Normal Mode only. 7.1.2. B REAKPOINT S UPPORT The monitor utilises the Address Break Controller for code located in ROM, allowing a single breakpoint to be set in the code.

7.1.5. B AUD R ATE S ETTING HMON has initially set to connect at 115200Baud. Should the user wish to change this, the value for the BRR in HMONserialconfiguser.c will need to be changed and the project re-built. Please refer to the HMON User Manual for further information.
