Data Packet (DP)
Contains 8 data bits and may be sent by the host or the ADBM-A350.
Host Driven Packets
The host initiates all data transmission with a START
condition. Next, slave address and register address
packets are sent. If there is a device address match, the
ADBM-A350 then responds to each Eight-bit data trans-
mission with an acknowledge signal (SDA = 0). Data is
transmitted with the most signifi cant bit fi rst.

To terminate the transfer of host driven packets, the host
follows the ADBM-A350’s ACK with a STOP condition. The
host can also issue a START condition after the ADBM-
A350’s ACK if it wants to start a new data transfer.
