I2C hardware master serial interface for asynchronous ADCs

The implementation of the I
²
C-compatible serial interface for asynchronous ADCs that output data irregularly in time is reported in the paper. The device contains I
²
C hardware master-transmitter functionality and is capable of operating fully autonomously in I
²
C bus communication system. In particular, the asynchronous ADC with proposed I
²
C interface is able to initiate data transfer on the bus when new data are available on the converter output.
