(1) All inputs are tied to 0 V or to VCC. Outputs do not source or sink any current
(2) Not applicable for devices with HF crystal oscillator only.
(3) Characterized with a Golledge MS1V-TK/I_32.768KHZ crystal with a load capacitance chosen to closely match the required load.
(4) Low-power mode 3, 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),

(6) LCD works in LPM3 if internal charge pump and V
REF
switch mode are enabled. LCD driver pins are configured as 4 × 36 at 32‑Hz
frame frequency with external 32768‑Hz clock source.
(7) RTC periodically wakes up every second with external 32768‑Hz as source.
