Anleitung Zusammenfassung
Note: If JP11 and JP14 are open, the user has to supply an adequate analog voltage supply (AVcc and AVss) to the A/D-converter. If JP12 and JP13 are open, the resistors R16, R17, R20, and R21 define AVRH and AVRL. By default the resistor network (R16, R17, R20, and R21) is not mounted on the board. 3.5 Alarm Comparator (JP: 85) Potentiometer RP2 is connected to ALARM0 in order to evaluate comparator 0 of the microcontroller. Any voltage between VCC and GND can be set. Additionally the adjusted voltage can be measured at connector J2. JP78 One potentiometer can be connected to the ALARM0/AN8 Jumper Setting Description JP85 Closed Pin 26 (ALRAM0/AN8) of the MCU is connected to RP2 (ALARM0) Open Pin 26 (ALRAM0/AN8) of the MCU is not connected Table 3-4: Alarm Comparator © Fujitsu Microelectronics Europe GmbH - 17 -FMEMCU-UG-960014-10 SK-96370-144PMC-GDC User Guide Chapter 3 Jumpers and Switches 3.6 Reset Generation (JP: 33, 41, 46, 47, 48) In addition to the internal Power-On reset, the microcontroller can be reset by an external reset circuit (Voltage Monitor) and also by a RS232 interface. Refer to the chapter ‘LIN / UART Connectors (X5 or X9)’ for DTR / RTS selection. JP33 Selects X5 or X9 as reset source. JP41 The signal on the DTR/RTS line can be negated with this jumper. Remove the jumper in order to disable the RS232 reset circuit. JP46 Selects the mode of the reset button SW6. JP47 A voltage supply monitor allows monitoring of 1V8 or 2V5 power supply. JP48 Open this jumper if no external Reset shall be generated. In this case only the internal reset is active (e.g.: power-on). Jumper Setting Description JP33 1-2 X5 (UART0) is used to generate Reset (UART RESET) 2-3 X9 (UART2) is used to generate Reset JP41 1-2 No polarity inversion for the DTR/RTS signal (DTR / DTRx) 2-3 Polarity inversion for the DTR/RTS signal JP46 1-2 Reset is applied immediately when SW6 is pressed (Reset imm./delayed) 2-3 Reset is applied when SW6 is pressed > 2sec JP47 (Monitor 1V8 / 2V5) 1-2 The voltage supply monitor observes 1V8 2-3 The voltage supply monitor observes 2V5 JP48 (RST MCU) Closed External reset generation is active Open No external reset generation Table 3-5: Reset Connection By default, the external reset is enabled and set to immediate reset while the reset by UART is disabled. Note: While a reset signal is asserted the red Reset-LED LD13 is lit. During normal operation, this LED should be off! If JP41 (DTR/DTRx) is set, the UART RESET jumper (JP33) and the according DTR/RTS (JP23 and JP38) jumper have to be set, too. If the reset LED is steadily on, check the power supply input voltage and the settings for the reset-generation by UART.

Each of the two D-Sub connectors can be configured as LIN or RS232 interface. DTS or RTS can be selected as reset source, and RTS and CTS can be connected by a jumper, since some terminals and Flash programming tools need this connection. Pin 1 (Vs) of X5 and X9 can be connected to the voltage input of the board by jumpers in order to supply the LIN bus. 3.9.1 LIN-UART 0 (JP: 19, 21, 23, 25, 27, 28, 29, 31) Jumper Setting Description JP21 (RXD) 1-2 SIN0 is connected to RS232 transceiver 2-3 SIN0 is connected to LIN transceiver JP25 (TXD) 1-2 SOT0 is connected to RS232 transceiver 2-3 SOT0 is connected to LIN transceiver JP27 (RS232/LIN) 1-2 X5 pin 2 is con...
