The configuration registers to select a themistor temperature sensor and the measurement method are found at
Bank 0, Index 59h, 5Dh, and 5Eh.
7.3.3.2. Monitor Temperature from Thermal Diode (Voltage Mode)
The thermal diode D- pin is connected to AGND (pin 105), and the D+ pin is connected to the temperature sensor
pin in the W83627UHG. A 15-KΩ resistor is connected to VREF to supply the bias current for the diode, and the
2200-pF, bypass capacitor is added to filter high-frequency noise. The configuration registers to select a thermal
diode temperature sensor and the measurement method are found at Bank 0, Index 59h, 5Dh, and 5Eh.
