Four mailbox properties are implemented as follows: 1. Customer OTP: GET_CUSTOMER_OTP and SET_CUSTOMER_OTP 2. Device-specific private key: GET_PRIVATE_KEY and SET_PRIVATE_KEY. The customer OTP is located in the rows 36-43. The device-specific private key is located in the rows 56-63. The customer OTP can be locked with the magic numbers 0xffffffff 0xaffe0000 when running the SET_CUSTOMER_OTP mailbox command. Bit 6 of row 32 indicates this lock, which is undocumented. The lock also applies to the device-specific private key.
