Hello Jim, thanks for the answer. I use already the 1a-R Mode. I found out new perceptions. After I plug in my circuit to power supply it works fine but when I reset my uC (STM32F4) the old output data (9A 5D 00 00 00 00 9A 5D ...) where generated. It seems like an timing problem. Is there a configuration procedure for the chip ( LM98714 ), which I must follow? regards, Steffen
