1. CPU running with memory access, all I/O pins in input mode with a static value at V
2. Data based on characterization, not tested in production.
3. All I/O pins in input mode with a static value at V
4. Slow mode selected with f
5. Slow-Wait mode selected with f
6. All I/O pins in input mode with a static value at V
7. This consumption refers to the Halt period only and not the associated run period which is software dependent.

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).
