253 / 308 page ![]() ST7MC1/ST7MC2 253/308 SUPPLY CURRENT CHARACTERISTICS (Cont’d) 12.4.3 HALT and ACTIVE-HALT Modes 1. All I/O pins in push-pull output mode (when applicable) with a static value at VDD or VSS (no load), PLL and LVD dis- abled. Data based on characterization results, tested in production at VDD max. and fCPU max. 2. All I/O pins in input mode with a static value at VDD or VSS. Tested in production at VDD max and fcpu max with clock input OSC1 driven by an external square wave; VDD applied on OSC2 to reduce oscillator consumption. Consumption may be slightly different with a quartz or resonator. 12.4.4 Supply and Clock Managers The previous current consumption specified for the ST7 functional operating modes over temperature range does not take into account the clock source current consumption. To get the total device consump- tion, the two current values must be added (except for HALT mode).
