(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 and RTC clocked by ACLK 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
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.
(4) 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.
(5) LCDMx = 11 (4-mux mode), LCDREXT = 0, LCDEXTBIAS = 0 (internal 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)
Even segments S0,S2,... = 0, odd segments S1,S3,... = 1. No LCD panel load.
(6) LCDMx = 11 (4-mux mode), LCDREXT = 0, LCDEXTBIAS = 0 (internal biasing), LCD2B = 0 (1/3 bias), LCDCPEN = 1 (charge pump
enabled), VLCDx = 1000 (V_LCD = 3V,typ.), LCDSSEL = 0, LCDPREx = 101, LCDDIVx = 00011 (f_LCD = 32768 Hz / 32 / 4 = 256 Hz)
Even segments S0,S2,... = 0, odd segments S1,S3,... = 1. No LCD panel load.
