Pins termination
In order to guarantee the correct behavior of an STA662 based application it is mandatory to
properly terminate unused input and inout pins.
Since many of the STA662 pins have secondary/tertiary functions which depend on the
specific firmware configuration, it is strongly suggested to review the final application's
schematic with ST application engineer.
