(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 Seiko Crystal SC-32S 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),
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).
CPUOFF = 1, SCG0 = 1 SCG1 = 1, OSCOFF = 0 (LPM3),
fXT1 = 32768 Hz, fACLK = fMCLK = fSMCLK = 0 MHz
(6) RTC wakes every second with external 32768-Hz clock as source.
(7) Low-power mode 4, VLO, excludes SVS test conditions:
Current for RTC clocked by VLO included. RTC disabled. Current for brownout included. SVS disabled (SVSHE = 0).
CPUOFF = 1, SCG0 = 1 SCG1 = 1, OSCOFF = 1 (LPM4),
fXT1 = 32768 Hz, fACLK = fMCLK = fSMCLK = 0 MHz
(8) Low-power mode 4, XT1, excludes SVS test conditions:
Current for RTC clocked by XT1 included. RTC disabled. Current for brownout included. SVS disabled (SVSHE = 0).
CPUOFF = 1, SCG0 = 1 SCG1 = 1, OSCOFF = 1 (LPM4),
