1. IRROFF is set to V_DD, this value can be lowered to 1.7 V when the device operates in the 0 to 70 °C temperature range.
a reduced temperature range.
2. When the ADC is used, refer to Table 64: ADC characteristics.
3. It is recommended to power V_DD and V_DDA from the same source. A maximum difference of 300 mV between V_DD and
V_DDA can be tolerated during power-up and power-down operation.
4. If T_A is lower, higher P_D values are allowed as long as T_J does not exceed T_Jmax.
5. In low power dissipation state, T_A can be extended to this range as long as T_J does not exceed T_Jmax.
