4.4.2 Sleep Sequence

Upon completion of the use of the ECC204-TFLXAUTH by the system, it is recommended that the system issue a sleep sequence to put the device into Low-Power mode. This sequence consists of the proper device address followed by the value of 0x01 as the word address followed by a Stop condition. This transition to the Low-Power state causes a complete reset of the device’s internal command engine and input/output buffer. It can be sent to the device at any time when it is awake and not busy.
