Note 1: Low-Power mode on T1 osc. Low-Power mode is limited to 85°C.
2: BOR and HLVD enable internal band gap reference. With both modules enabled, current consumption will be
less than the sum of both specifications.
3: High-Power mode in T1 osc.
4: A/D converter differential currents apply only in RUN mode. In SLEEP or IDLE mode both the ADC and the FRC
turn off as soon as conversion (if any) is complete.
