3-wire protocol
For the 3-wire serial bus the first byte refers to the register address which is programmed. The second byte refers to the data to be sent to the chosen
register (see Table 1). The acquisition is achieved via SEN.
Using the 3-wire interface, an indefinite number of ICs can operate on the same system. Pin SEN is used to validate the circuits.
