(1) All inputs are tied to 0 V or to VCC. 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 ACLK and RTC clocked by XT1 included. ACLK = low-frequency crystal operation (XTS = 0,
XT1DRIVEx = 0).
CPUOFF = 1, SCG0 = 1, SCG1 = 1, OSCOFF = 0 (LPM3); fACLK = 32768 Hz, fMCLK = fSMCLK = fDCO = 0 MHz
Current for brownout, high-side supervisor (SVSH) normal mode included. Low-side supervisor and monitors disabled (SVSL, SVML).
High-side monitor disabled (SVMH). RAM retention enabled.
(4) 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 (fLCD = 32768 Hz / 32 / 4 = 256 Hz)
Even segments S0, S2, ... = 0 and 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 = 1 (charge pump
enabled), VLCDx = 1000 (VLCD = 3V,typ.), LCDSSEL = 0, LCDPREx = 101, LCDDIVx = 00011 (fLCD = 32768 Hz / 32 / 4 = 256 Hz)
Even segments S0, S2, ... = 0 and odd segments S1, S3, ... = 1. No LCD panel load.
