IPS2200 Cyber security Reset Problem.

Question

Hello. 
 When using IPS2200, if I2C Write is prohibited, is there a way to reset it? 
 If Cyber ​​Security is activated (Bit 6 of Register 0x01/ 0x21 System Configuration 2), Register Write is no longer possible, making it difficult to use the chip. 
 If Cyber ​​Security is activated, is there a way to change it back to disabled?

Hello sir, 
 Let me provide you the feedback I received about this from the Application Engineering Team: 
 Once this bit is flipped to read only, then there is no more option to write again. This is the expected function of this bit. If you have locked it before calibrating or programming the chip, the chip unit needs to be scrapped and replaced with a new one.
