126.96.36.199 Level1 Protection
To write to a Level1 protected register, follow these steps:
- Write the address of the destination register, XORed with the protection password (0x7D) to the PASSWORD register.
- Write data to the password-protected register.
- Data is only transferred to the protected register if the content of the PASSWORD register XORed with the address sent in Step 2 matches 0x7D. Otherwise, the transaction is ignored. The PASSWORD register is reset to 0x00 after the transaction regardless of whether the XOR logical function matched 0x7D or not.
The cycle must be repeated for any other register that is Level1 write protected.
