benutzt siehe in beigefuegter Datei ===============etwas was man verstehen und beachten sollte.... 3.When the PIC reads a port register, it doesn’t read the value in the “output latch” (i.e. the value you wrote to it). Instead, it reads the pins themselves – the voltages present in the circuit. ======
vom Eingang: "Read-Modify-Write Feature Some instructions that read a port read the latch and others read the pin. Read-modify-write instructions read the latch rather than the pin, and these instructions read a value, possibly change it, and then rewrite it to the latch."

Storage precautions When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps.

Half Wave Rectifier For a low frequency positive input signal, 100% negative feedback is applied when the diode conducts. The forward voltage is effectively removed by the feedback, and the inverting input follows the positive half of the input signal almost perfectly. When the input signal becomes

shows the effect of cross−conduction prevention. 2. This section of the timing diagram shows that when the voltage on VDD decreases sufficiently all gate output signals will go low, switching off all six IGBTs. When the voltage on VDD rises sufficiently, normal operation will resume. 3. This section shows that when the bootstrap voltage on VB(U) (VB(V), VB(W)) drops, the corresponding high side output U (V, W) is switched off. When the voltage on VB(U) (VB(V), VB(W)) rises sufficiently, normal operation will resume
