6.8 Temperature Sensor Controller Registers
The temperature sensor controller registers are used to access the internal temperature
sensor registers.
Refer to Section 5.12, “Temperature Sensor Controller" for a definition of the parameters
“m1”, “m2”, and “a”, and how they are used to calculate the 820x die temperature.
6.8.1
TSC Address Register
The TSC Address register is used to set the temperature sensor register address. The host
should set the TSC address before a reading or writing to the 820x temperature sensor.

TSC Data Register
The TSC Data register is used to store the data read from the temperature sensor or store
the data to be written to the temperature sensor. Note that the host should set the TSC
address using the TSC Address register before issuing a read or write register command.
Refer to Section 5.12, “Temperature Sensor Controller" for a definition of the parameters
“m1”, “m2”, and “a”, and how they are used to calculate the 820x die temperature.
