(1) All inputs are tied to 0 V or to V_CC. Outputs do not source or sink any current.
(2) The currents are 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.
(3) Current for watchdog timer clocked by SMCLK included. ACLK = low frequency crystal operation (XTS = 0, XT1DRIVEx = 0).
CPUOFF = 1, SCG0 = 0, SCG1 = 0, OSCOFF = 0 (LPM0); f_ACLK = 32768 Hz, f_MCLK = 0 MHz, f_SMCLK = f_DCO = 1 MHz
(4) Current for brownout, high-side supervisor (SVS_H) normal mode included. Low side supervisor and monitors disabled (SVS_L, SVM_L).
High side monitor disabled (SVM_H). RAM retention enabled.
(5) Current for watchdog timer and RTC clocked by ACLK included. ACLK = low frequency crystal operation (XTS = 0, XT1DRIVEx = 0).
CPUOFF = 1, SCG0 = 0, SCG1 = 1, OSCOFF = 0 (LPM2); f_ACLK = 32768 Hz, f_MCLK = 0 MHz, f_SMCLK = f_DCO = 0 MHz; DCO setting
= 1 MHz operation, DCO bias generator enabled.
(6) Current for watchdog timer and RTC clocked by low frequency clock included. ACLK = low frequency crystal operation (XTS = 0,
XT1DRIVEx = 0).
CPUOFF = 1, SCG0 = 1, SCG1 = 1, OSCOFF = 0 (LPM3); f_ACLK = 32768 Hz, f_MCLK = f_SMCLK = f_DCO = 0 MHz
(7) Current for watchdog timer and RTC clocked by low frequency clock included. ACLK = VLO.
CPUOFF = 1, SCG0 = 1, SCG1 = 1, OSCOFF = 0 (LPM3); f_ACLK = f_VLO, f_MCLK = f_SMCLK = f_DCO = 0 MHz
(8) CPUOFF = 1, SCG0 = 1, SCG1 = 1, OSCOFF = 1 (LPM4); f_DCO = f_ACLK = f_MCLK = f_SMCLK = 0 MHz
(9) f_DCO = f_MCLK = f_SMCLK = 0 MHz, f_ACLK = 32768 Hz, PMMREGOFF = 1, RTC active on AUXVCC3 supply
(10) f_DCO = f_MCLK = f_SMCLK = 0 MHz, f_ACLK = 0 Hz, PMMREGOFF = 1
