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 v
