Start Log - #22

The START LOG command starts the logging procedure and sets

the Start time in UTC format. In logging state the chips

automatically performs the measurements and data logging in

the specified time intervals. Supported is also a delayed start,

which means that the chip will start with the logging procedure

with a specified delay after it receives the START LOG command.

This command also starts the Interrupt mode of operation

where the measurements and data-logging are driven from

external events.

Get Log State - #23

The GET LOG STATE command gets the log state of following

parameters: measurement status and out of limits counter. This

gives the ability to quickly check the state of the package

without the need to read the whole temperature data log.

Get Calibration Data - #24

The GET CALIBRATION DATA command reads the calibration

data for the internal and external sensors.

Get Battery Level - #25

The GET BATTERY LEVEL command measures and reads the

voltage level of the battery.

Set Shelf Life - #26

The SET SHELF LIFE command writes the shelf life algorithm

parameters and enables the dynamic shelf life calaculation.

Initialize - #27

The INITIALIZE command sets the size of the application data

area and sets the delay time. The command clears the

measurement status and limits counter blocks.

Get Sensor Value - #28

The GET SENSOR VALUE command measures and backscatters

the value of the specified sensor – internal, external 1 or

external 2.

Open Area - #29

The OPEN AREA command opens the specified area of the

memory (System, Application, and Measurement). The

password is stored in a RAM location and compared with the

password in EEPROM. When the tag leaves the RF field, this RAM

location is cleared.

Access FIFO - #30

The ACCESS FIFO command can read or write the 8-byte FIFO.

The FIFO can also be accessed from the SPI so this command

can be used for fast data transfer between a microcontroller

connected to the SPI and an RFID reader.
