10.4 SUPPLY CURRENT CHARACTERISTICS
The following current consumption specified for
the ST6 functional operating modes over tempera-
ture range does not take into account the clock
source current consumption. To get the total de-
vice consumption, the two current values must be
added (except for STOP mode for which the clock
is stopped).
