Write Operation
A Write operation requires a START condition, followed by a valid
Identification Byte, a valid Address Byte, a Data Byte, and a STOP
condition. After each of the three bytes, the ISL23325 responds
with an ACK. The data is transferred from I2C block to the
corresponding register at the 9th clock of the data byte and the
It is possible to perform a sequential Write to all DCP channels
via a single Write operation. The command is initiated by sending
an additional Data Byte after the first Data byte instead of
sending a STOP condition.
Read Operation
A Read operation consists of a three byte instruction followed by
one or more Data Bytes (see Figure 30). The master initiates the
operation issuing the following sequence: a START, the
Identification byte with the R/W bit set to “0”, an Address Byte, a
second START, and a second Identification byte with the R/W bit
set to “1”. After each of the three bytes, the ISL23325 responds
with an ACK; then the ISL23325 transmits Data Byte. The master
terminates the read operation issuing a NACK (ACK) and a STOP
condition following the last bit of the last Data Byte (see
Figure 30).
