8.4 Configuration register
8.5 Temperature register
At power-up, the pointer value is preset to logic 0 for register Temp; users can then read
the temperature without specifying the pointer byte.
The Configuration (Conf) register is a read/write register and contains an 8-bit
non-complement data byte that is used to configure the device for different operating
conditions.
Table 6.
Legend: * = default value.
The Temperature (Temp) register holds the digital result of temperature measurement or
monitor at the end of each analog to digital conversion. This register is read only and
contains two 8-bit data bytes consisting of one Most Significant Byte (MSByte) and one
Least Significant Byte (LSByte). However, only 13 bits of those two bytes are used to store
the Temp data in two’s complement format with the resolution of 0.03125 C.
shows the bit arrangement of the Temp data in the data bytes.
