To achieve the best results when using the device,
decouple the V
Use a high-quality, ceramic, surface-mount capacitor
if possible. Surface-mount components minimize lead
inductance, which improves performance, and ceram-
ic capacitors tend to have adequate high-frequency
response for decoupling applications.
Decouple the REG25 and REG18 regulator outputs using
1FF and 10nF capacitors (one each per output).
Do not connect other circuitry to either of these pins.

Clearing and setting this bit reinitializes the temperature sensor.
0 = Temperature sensor disabled.
1 = Temperature sensor enabled.
These bits always return a 0.
MSDA, MSCL, SCL, SDA, FAULT, and ALERT are open-
drain pins and require external pullup resistors con-
nected to V
