Note:
1. 32768Hz is in slow start mode (RTCC.4=1) for the D.C. current measurement.
2. fS is the internal clock for Buzzer, RTC, Time base and WDT.
3. Both Timer/Event Counters are off. Timer filter is disabled for all test conditions.
4. All peripherals are in OFF condition if not mentioned at IDD,ISTB tests.
