Table 28. I2C Password location Block Address NFC I2C Byte 0 Byte 1 Byte 2 Byte 3 Description 33h 1033h I2C_PWD0_ 0 (LSB) I2C_PWD0_1 I2C_PWD0_2 I2C_PWD0_ 3 (MSB) Read Password 34h 1034h I2C_PWD1_ 0 (LSB) I2C_PWD1_1 I2C_PWD1_2 I2C_PWD1_ 3 (MSB) Write Password 35h 1035h I2C_ PWD2_ 0 (LSB) I2C_PWD2_1 I2C_PWD2_2 I2C_PWD2_ 3 (MSB) AREA_1 Read Password 36h 1036h I2C_ PWD3_ 0 (LSB) I2C_PWD3_1 I2C_PWD3_2 I2C_PWD3_ 3 (MSB) AREA_1 Write Password Password authentication from I2C perspective is done by using I2C write command with the password to the I2C Key authenticate location. This will make the I2C logic to enter the Authenticated state if the key matches with the respective key. Table 29.

The memory access may be protected by plain password depending on the access conditions. The programming of I2C Key Header can be done in only one direction from lower state to higher state and it is irreversible. The NFC interface can access this block with READ CONFIG and WRITE CONFIG commands if not locked by NFC section lock. Once locked as per table below, I2C_KH cannot be updated from the NFC interface anymore. |
