Some SPI devices use the term. To distinguish from 'two wire' (I2C), and 'one wire' connections (like the Dallas parts). Best Wishes

Ah, but the 600VDC supply makes it a bit dodgy for Boki who can't even manage Google.

Hi,

Thanks, I think that should be SPI.

Finally, it is a little trouble, I have to code the clock for 3-wire bus, right?

I will choose I2C now..
