Note:
1. LXT is in slow start mode (RTCC.4=QOSC=1) for the D.C. current measurement.
2. fS is the internal clock for the Buzzer, RTC Interrupt, Time Base Interrupt and the 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.
