ADBM-A350 Driven Packets
By request of the host, the ADBM-A350 acknowledges a read request and then outputs a data byte transmitting the
most signifi cant bit (7) fi rst. If the host intends to continue the data transfer, the host acknowledges the ADBM-A350. If
the host intends to terminate the transfer, it responds with not acknowledge (SDA = 1), and then drives SDA to generate
a STOP condition. The host can also drive a START condition if it wants to begin a new data transfer with the same ADBM-
A350.

Example: Writing Data to Sensor Registers
The host writes a value of 0x02 to address 0x07 in the following illustration.
The example ADBM-A350 address is 0x57.
