Where’s this frequency coming from?

There's an oscillator on the main board that goes out to the keyboard PCB (it's hard to make out in the schematic because of the poor scan quality, but the parts list makes it more clear)

You’re supposed to use _XTAL markup for those. I’ll fix it.

Even for ceramics?

Yeah, if it’s a crystal/resonator, use _XTAL markup. If it’s an RC/LC circuit or something, just put in the frequency.

Yes xtal.cpp includes ceramic oscillators.

Good to know, thanks.

The code looked fine after a quick skim. I’d just like clarification on where that MSM6200 clock frequency comes from. |
Also some fixes to the uPD934 and MSM6200.
