Note: 1. 32768Hz is slow start mode (RTCC.4=1) in D.C. current measurement.
2. LCD waveform is in Type A condition.
3. fS is internal clock for Buzzer, RTC, Time base and WDT.
4. Timer0/1 off. Timer filter disable in all test condition.
5. All peripherals are in OFF condition if not mentioned at IDD, ISTB tests.
