receiver pulls the SDA line LOW to acknowledge the
reception of the eight bits of data (See Figure 13).
The ISL1208 responds with an ACK after recognition of a
START condition followed by a valid Identification Byte, and
once again after successful receipt of an Address Byte. The
ISL1208 also responds with an ACK after receiving a Data
Byte of a write operation. The master must respond with an
ACK after receiving a Data Byte of a read operation.
