AS5600 magnetic sensor in analog mode

Hello
I tried to program AS5600 using out pin, I did it as 0-180 degrees but the analog output always remain at 5V. if I turn the magnet I can read the angle value from registers using i2c and it works correctly. I don't know how to activate the analog output. I tried to write value 0x08 in MANG_H register but I couldn't write it. you can see the registers value in both state 0 and 180 degree in the attached file.
any Idea?
