(1) Current for watchdog timer clocked by ACLK and RTC clocked by XT1 included. Current for brownout included. SVS disabled (SVSHE = 0).
CPUOFF = 1, SCG0 = 1 SCG1 = 1, OSCOFF = 0 (LPM3),
fXT1 = 32768 Hz, fACLK = fXT1, fMCLK = fSMCLK = 0 MHz
Activating additional peripherals increases the current consumption due to active supply current contribution as well as due to additional idle current - idle current of Group containing LCD module already included. Refer to the idle currents specified for the respective peripheral groups.
