Control data is entered in the standard I2C BUS format. The device contains 1 addressable current limited output and 4 addressable bi–directional open collector ports one of which is a 3 bit ADC. The information on these ports can be read via the I2C BUS. The device has one fixed I2C BUS address and 3 programmable addresses, programmed by applying a specific input voltage to the P3 current limited output. This enables 2 or more synthesisers to be used in a system.
