Dear all!

Can anybody help me? I tried to used I2C and came across with one problem: I set SII, then I set STA bit (start condition), then I load S2DAT register and it sends this 8-byte serie. But after it, both SDA and SCL are in ''0'' state, while they need to be at ''high-impedance'' state.

No device is connected to I2C from another side (uPSD3212 is the only device) and interrupts are disabled. Can we try I2C in such condition? Do you have any ASM-code exampple of I2C usage?

Thank you in advance.
