PRODUCTION DATA
Temperature data is represented by a 14-bit, two's complement word with an LSB (Least Significant Bit) equal to 0.03125 °C. The last two bits of the register are always 00.

The first data byte is the most significant byte with most significant bit first, permitting only as much data as necessary to be read to determine temperature condition. For example, if the first four bits of the temperature data indicate an over temperature condition, the host controller could immediately abort communication and take action to remedy the excessive temperature condition.
