Markus, 100us is long enough for FAULTRES. It sounds as if NRESET might be accidentally getting toggled instead of FAULTRES. Can you check the state of NRESET on the oscilloscope when you run this procedur? The only way for the registers to reset to the default configuration is: 1: send a command to reload EEPROM 2: toggle NRESET 3: reset power Also, when you toggle FAULTRES back to high, what is the state of the FAULT pin? Thanks, -Clancy
