Supply current characteristics
The following 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 consumption, the two current values must be added (except for Halt mode
for which the clock is stopped).

2.
Measurements are done in the following conditions:
- Program executed from RAM, CPU running with RAM access.
- All I/O pins in input mode with a static value at VDD or VSS (no load)
- All peripherals in reset state.
- Clock input (OSC1) driven by external square wave.
- In Slow and Slow Wait mode, fCPU is based on fOSC divided by 32.
To obtain the total current consumption of the device, add the clock source (Section 11.5.1) and the
peripheral power consumption (Section 11.4.2).
