After LED has been lit, change of TUP becomes available from 1AH register at an address (to be described
later) of I
[5] Delay in LED current change
S1F76680 allows providing delay to the LED current change waveform and thus realizing a smoother
current change by connecting the capacitor CLED to CLED pin. Connection of CLED=1µF is
recommended.
