4. EDK OPERATION 4.1. USER INTERFACE The EDK provides two buttons for influencing the operation of the board. The purpose of each button is clearly marked next to it. Refer to the board layout for positions (Section 3) 1. Reset Switch This button provides the microcontroller with a reset pulse utilizing the built in power on reset control of the device. 2. NMI Switch This button provides a de-bounced signal to the microcontroller for each operation of the button. There is no max

4.2.2. CRYSTAL CHOICE The operating crystal frequency has been chosen to support the fastest 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. It also confirms the resultant baud rate and the bit error rate that can be expected. Baud Rate Register Settings for Serial Communication Rates

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 INTERFACE The board has been tested with an Philips TJA1020TD device (Not supplied). The device should be connected to P71 and P72 using 0R links on R29 and R31. Alternative connections are available; refer to section 5.3 for more information. The links R41, R45 and R47 need to be c

5. BOARD OPTIONS 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 described in sections 5.2. The additional zero-ohm links provide additional features that may be required to interface with other systems. All the Jumper link settings are three pin options. There are four sets of options on each header. The headers are numbered from 1 to 12 with pin 1 marked on the PCB by an

5.3. OPTION LINK SELECTION The following sections show the option links that apply to each peripheral 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. O – Groups of options which if fitted must be connected in the groups as shown by the table row. S – Optional selection that will enable or disable specific device functions as listed. ! – Options which when incorrectly f

5.3.3. SPI – SERIAL PERIPHERAL INTERFACE The SPI interface is not directly compatible with the SCI interface on the device. Selection of the connections to the SPI interface should therefore be chosen to allow the operation of other peripherals as required.

7. CODE DEVELOPMENT 7.1. HMON 7.1.1. MODE SUPPORT The HMON library is built to support Normal Mode only. 7.1.2. BREAKPOINT SUPPORT The monitor utilises the Address Break Controller for code located in ROM, allowing a single breakpoint to be set in the code. Code located in RAM may have multiple breakpoints limited only by the size of the On-Chip RAM. Due to a limitation of the internal address break controller, a breakpoint set in ROM will execute the instruction at the breakpo

7.1.5. BAUD RATE SETTING 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. 7.1.6. INTERRUPT MASK SECTIONS The EDK3687 has fixed interrupt priorities. The serial (SCI3 )port interrupt is used by HMON. The Real Time clock, external interrupt and Timer V interrupts have a higher priority th
