I want to write data to the MEMORY-DATA register, but no matter what value I write to the MEMORY-DATA register, the value I read is a default value, which means I did not successfully write to the MEMORY-DATA register. I have found the description of the MEMORY-DATA register, which indicates that the writing of the MEMORY-DATA register is protected by the KEY-CFG register. Therefore, I would like to see the description of the KEY-CFG register, but I cannot find any content about the KEY-CFG register in the chip manual. Can you help me find any description about the KEY-CFG register?
Thank you.
