I want to connect LCD to the ST using VLCD pin , but instead of 3V i need 4.5 V.
I found in data sheet that there is stepup converter (kind of SW configurable DC2DC)  that can be used for this purpose but i couldn't find any other information - how to handle it by software.

1) is it correct ?
2) if yes, how to configure it.

Thanks in advance ,
