Synchronous 2-wire Serial Interface
The synchronous mode is the default after powering up V CC due to an internal pull-up on RST. For embedded
applications using CryptoMemory in standard plastic packages, this is the only communication protocol.
? Power-up V CC , RST goes high also.
? After stable V CC , CLK-SCL and I/O-SDA may be driven.

Note :
Five clock pulses must be sent before the first command is issued.

Communication Security Modes
Communications between the device and host operate in three basic modes. Standard mode is the default mode for
the device after power-up. Authentication mode is activated by a successful authentication sequence. Encryption mode
is activated by a successful encryption activation following a successful authentication.
