Summary of Power-On Default

The MCP98244 has an internal Power-On Reset

(POR) circuit. If the power supply voltage VDD glitches

down to the VPOR_TS and VPOR_EE thresholds, the

device resets the registers to the power-on default

settings.

Table 5-8 shows the power-on default summary for the

temperature sensor. The EEPROM resets the address

pointer to 0x00 hex.
