ADD pin
With this pin it is possible to select one of the 4 possible I²C slave addresses. Neither
internal pull-up nor pull-down is provided. The pin has to be connected to either GND, VI,
SCL or SDA to select the desired I²C slave address (see Table 7)
7.3.5
TMSK pin
This pin can be used to implement the TX masking function. This function has effect for flash
current settings higher than 100 mA (bit FDIM_3=1) only. Under this condition, when this pin
is pulled high by the microprocessor, the current flowing in the LED is forced at 100 mA typ.
Neither internal pull-up nor pull-down is provided. This pin must be externally wired to GND
if TX masking function is not used.
