SWITCHES, JUMPERS, AND LEDS CHAPTER 2 SW4, SW5, SW7, and JP1 SW4 and SW5 are a DIP switch to select an operation mode. SW7 is a slide switch to select an operation mode. JP1 is a jumper to select a power source. 2.1.1 Flash Programming Mode Flash EEPROM on the 78K0/KF1+ MCU can be programmed using the attached software “PG-FPL”...
CHAPTER 2 SWITCHES, JUMPERS, AND LEDS 2.1.2 On-chip Debug Mode The following setting activates the On-chip debug functions on the MCU. You can debug your program code in the Flash EEPROM, if your PC is connected to the MCU board via USB. On-chip debug mode Bit 1 Bit 2...
CHAPTER 2 SWITCHES, JUMPERS, AND LEDS SW1is a 4 directional switch with center push. If it is directed or pushed, the P7*/KR* input is set to GND. Otherwise the circuit is open. Therefore please set the on-chip pull-up resistors at P7*/KR* during initializing routine of your program code.
CHAPTER 2 SWITCHES, JUMPERS, AND LEDS JP2 defines the signal level, 5V or 3.3V, of the I/O expansion, CN3. JP2 Settings 5.0V Marked as 5.0V: Pin 1 3.3V Marked as 3.3V: Pin 3 LED4 LED4 is the power indicator. LED1, LED2, and LED3 LED1, LED2, and LED3 are available for applications.
CHAPTER 2 SWITCHES, JUMPERS, AND LEDS Jumper on the CC2420EM board Please set the jumper on the CC2420EM board as shown in the schematic below. For details of the CC2420EM board, please contact Chipcon AS at www.chipcon.com. UM U17586EE1V0UM00...
POWER SUPPLY CHAPTER 3 There are two choices to supply power to the board, USB or a 006P battery via CN2. Please refer to 2.1.3 JP1 for the jumper setting. Please replace the battery with a new one, if the voltage level goes down to 6.5V. Below the voltage level of 6.5V, functions of the board are not guaranteed.
