We don't want to use I2C, in TDA7577BLVPD

We want to use TDA7577BLVPD in legacy mode how can we set gain to 16dB in legacy mode?

I could not find any reference in parts datasheet

Welcome @Atharvraa, to the community!

Since the legacy mode is controlled via the two pins ST-BY and MUTE, not all functions offered by I2C control can be implemented. Details can be found in the data sheet, section 7.
