I2C Slave on ATtiny841

Question

I am using an ATtiny841 microcontroller as an I2C slave, but I have difficulty finding information on it. So for, all I have are application notes and reference code for TWI and USI module.

It seems like ATtiny841 has a unique TWI slave interface, which is slightly different. Although I could write out the code manually it would really help if there is a standard sample code that I can refer to.

Any suggestions?

Thanks in advance.

@Ignacio: Yes, AVR311 is the one that I'm currently referring to. It is based on the more general TWI module found in ATmega controllers. — bot3663369, Mar 17 '15 at 04:13
@vicatcu: I have used USI on other ATtiny controllers, but 841 does not have USI. — bot3663369, Mar 17 '15 at 04:16

You should be able to use the TWI example code as-is, since TWI is I2C: What is difference between I2C and TWI?
