YM connection. What, where and how do you need it?

Hello fan Hello! When connecting YM, I wanted to take the frequency directly from the Z80 (as, for example, in the diagram fan'a, if I'm not mistaken) and divide using the |SEL connection, but here they say that this cannot be done, because it’s loading uh... in general, something is loading :D and You need to take the frequency directly from the clock generator. If this is so, then I would like to know, and DA0-DA7 for YM-ki will also have to be taken from Are there any different places on the diagram or can DA0-DA7 be taken from the processor? Thank you!
