APPLICATION INFORMATION
temperature registers (TMPH, TMPL)
The TMPH (address 0x61) and the TMPL registers (address 0x60) reports die temperature in hex format in units
of 0.25_K.The temperature is reported as 11 bits of data, using all 8 bits of the TMPL low register and the 3 bits
of the TMPH register. The temperature should be read as the concatenation of TMPH [2:0] and TMPL [7:0],
0.25_K/LSB. The 5 MSBs of TMPH, TMPH [7:3], are cleared on POR and are reserved. The 5 bits should also
be masked off when reading the temperature, to ensure that incorrect data is not used when calculating the
temperature.
