(1) Current measured into VCC.
(2) All other input pins tied to 0 V or VCC. Outputs do not source or sync any current.
(3) CPU is OFF, flash powered down.
(4) Bank 0 of SRAM retained, all other banks powered down.
(5) See
Table 5-51 for details on additional current consumed for each extra Bank that is enabled for retention.
(6) WDT module is disabled.
(7) RTC sourced by LFXT. Effective load capacitance of LF crystal is 3.7 pF.
(8) LCDMx = 11 (4-mux mode), LCDREXT = 1, LCDEXTBIAS = 1 (external biasing), LCD2B = 0 (1/3 bias), LCDSSEL = 0, LCDPREx = 101, LCDDIVx = 00011 (fLCD = 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.
(9) LCDMx = 11 (4-mux mode), LCDREXT = 0, LCDEXTBIAS = 0 (internal biasing), LCD2B = 0 (1/3 bias), LCDSSEL = 0, LCDPREx = 101, LCDDIVx = 00011 (fLCD = 32768 Hz / 32 / 4 = 256 Hz) Even segments S0, S2, ... = 0, odd segments S1, S3, ... = 1. No LCD panel load.
(10) SVSMH is disabled.
