(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),
f_XT1 = 32768 Hz, f_ACLK = f_XT1, f_MCLK = f_SMCLK = 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.
(2) LCDMx = 11 (4-mux mode), LCDREXT = 1, LCDEXTBIAS = 1 (external biasing), LCD2B = 0 (1/3 bias), LCDCPEN = 0 (charge pump
disabled), LCDSSEL = 0, LCDPREx = 101, LCDDIVx = 00011 (f_LCD = 32768 Hz / 32 / 4 = 256 Hz)
Current through external resistors not included (voltage levels are supplied by test equipment).
Even segments S0, S2,... = 0, odd segments S1, S3,... = 1. No LCD panel load.
