I2C-bus and 3-wire serial bus interface
The I2C-bus and 3-wire serial buses control the status of the different control DACs and registers. Control pin DIS
enables or disables the full serial interface function (disable at HIGH level). Four ICs can be used in the same system
and programmed by the same bus. Therefore, two pins (ADD1 and ADD2) are available to set each address respectively,
for use with the I2C-bus interface. All programming is described in Chapter “I2C-bus and 3-wire serial bus interfaces”.
