ADD pin
With this pin it is possible to select one of the 4 possible I
pull-up nor pull-down is provided. The pin has to be connected to either GND, V
SDA to select the desired I
It is necessary to keep SCL and SDA high during power on reset, otherwise the I
address may be recognized improperly.
TMSK pin
This pin can be used to implement the T
Flash current settings higher than 200 mA (bit FDIM_3=1). Under this condition, when this
pin is pulled high by the µP, the current flowing in the LED is forced at 200 mA typ. No
internal pull-up nor pull-down is provided; to be externally wired to GND if T
function is not used.
I
Data transmission from the main µP to STCF03I and vice versa takes place through the 2
I
positive supply voltage must be externally connected). The recommended maximum voltage
of these signals should be 3.0 V.
