Hi Team,
Our customer would like to know about direct PWM control.
------------
[Q1]
Is the LED current set by “PWM register” the following values at the direct PWM control mode?
So, I understand this current value is related to “CURRENT register”
Is my understanding correct?
4. Write PWM values:
– Write to address 02H 1000 0000b (R driver PWM 50% duty cycle) -> ILED=17.5mA*0.5=8.75mA
– Write to address 03H 1100 0000b (G driver PWM 75% duty cycle)-> ILED=17.5mA*0.75=13.125mA
– Write to address 04H 1111 1111b (B driver PWM 100% duty cycle)-> ILED=17.5mA*1.0=17.5mA
Default LED current (17.5 mA) is used for LED outputs, if no other values are written.

[Q2]
According to datasheet, “Default LED current (17.5 mA) is used for LED outputs, if no other values are written.”
However, they would like to change the value of “CURRENT register”.
Could you please let us know the program timing of “CURRENT register”?
I guess that this timing is “Add program”.
Is my understanding correct?
