To set the value of the Pointer Register, the Master must first initiate a START condition followed
by the AT30TS750’s device address byte (1001AAA0 where “AAA” corresponds to the hard-wired
A2-0 address pins). After the AT30TS750 has received the proper address byte, the device will
send an ACK to the Master.
The Master must then send the appropriate data byte to the
AT30TS750 to set the value of the Pointer Register.
After device power-up or reset, the Pointer Register defaults to 00h which is the Temperature
Register location; therefore, the Temperature Register can be read from immediately after device
power-up or reset without having to set the Pointer Register. If the device is configured to power-
up in the Shutdown Mode, then the device will make a single temperature measurement
immediately after power-up so that valid temperature data can be output from the Temperature
Register.

Temperature Register
The Temperature Register is a 16-bit read-only register that stores the digitized value of the most
recent temperature measurement.
The temperature data value is represented in the 2’s
complement format, and, depending on the resolution selected, up to 12 bits of data will be
available for output with the remaining LSBs being fixed in the logic “0” state. The Temperature
Register can be read at any time, and since temperature measurements are performed in the
background, reading the Temperature Register does not affect any other operation that may be in
progress.
The MSB (bit 15) of the Temperature Register contains the sign bit of the measured temperature
value with a “0” indicating a positive number and a “1” indicating a negative number.
The
remaining MSBs of the Temperature Register contain the temperature value in the 2’s
complement format.
Table 6-3 details the Temperature Register format for the different
selectable resolutions, and Table 6-4 shows some examples for 12-bit resolution Temperature
Register data values and the associated temperature readings.
