Interface for Slave
The master must generate a “ Start ”, by sending the 7-bit
slave address plus a 0 and wait for acknowledge from
DS90C387R. When DS90C387R acknowledges (the 1st

ACK) that the master is calling, the master then sends the
data register address byte and waits for acknowledge from
the slave. When the slave acknowledges (the 2nd ACK), the
master sends the data byte and wait for acknowledge from
the slave. When the slave acknowledges (the 3rd ACK), the
master generates a “ Stop ”. This completes the “ WRITE ”.
