MCP9808
5.3
Summary of Power-on Default
The MCP9808 has an internal Power-on Reset (POR)
circuit. If the power supply voltage, V
DD
, glitches below
the V
POR
 threshold, the device resets the registers to
the power-on default settings.
Table 5-3 shows the power-on default summary for the
Temperature Sensor registers.
