6.     Register Descriptions
This section describes all the temperature sensor registers that are used in the Atmel
?/DIV>
 AT30TS00. The
AT30TS00 has several registers that are user accessible and or programmable and used for latching temperature
readings, storing high and low temperature limits, configuring the hysteresis threshold and reporting status.
These registers include the Capability Register, Upper Alarm Trip Register, Lower Alarm Trip Register, Critical
Alarm Trip Register, Temperature Register, Manufacturer Identification Register, Device Identification Register
and SMBus Register. The AT30TS00 uses an 8-bit Pointer Register to access these 16-bit data registers.
Table 6-1 below, indicates the Write / Read access capability of each register. Please note that reading from a
write only register will result in reading 0 data and writing to read only register will have no impact even though
the write sequence was acknowledged by the device.

6.1.    Address Pointer Register
The AT30TS00 uses a Pointer Register to select and access the 16-bit data registers shown in
Table 6-1. The Pointer Register is an 8-bit write only register (See Table 6-2). The power on default value is 00h
which is the address location for the capability register.
