Yes I have two separate +5V. It is for coded caraudio. When I reprogram eeprom for immo off and connect +5V to WP pin of eeprom carradio is working but memory station is not working, also settings for audio dont work, all data that are usualy stored to eeprom.
I need to disable writing just for first few secconds when MCU is checking one location in e2prom.
My mistake
