9.3 3W-bus protocol
t s3W = 100 ns
For the 3W-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
Using a 3W-bus interface, an indefinite number of ICs can operate on the same
system. Pin SEN is used to validate the circuits.
