(1) All inputs are tied to 0 V or to VCC. Outputs do not source or sink any current.
(2) Not applicable for MCUs with HF crystal oscillator only.
(3) Characterized with a Micro Crystal MS1V-T1K crystal with a load capacitance of 12.5 pF. The internal and external load capacitance are chosen to closely match the required 12.5-pF load.
(4) Low-power mode 3, 12.5-pF crystal, includes SVS test conditions:
Current for watchdog timer clocked by ACLK and RTC clocked by XT1 included. Current for brownout and SVS included (SVSHE = 1).
CPUOFF = 1, SCG0 = 1 SCG1 = 1, OSCOFF = 0 (LPM3),
fXT1 = 32768 Hz, fACLK = fXT1, fMCLK = fSMCLK = 0 MHz
(5) Low-power mode 3, VLO, excludes SVS test conditions:
Current for watchdog timer clocked by VLO included. RTC disabled. Current for brownout included. SVS disabled (SVSHE = 0).
