PRELIMINARY TECHNICAL DATA
If the operation is a write operation, the first data byte
after the slave address is a command byte. T his tells the
slave device what to expect next. It may be an instruc-
tion such as telling the slave device to expect a block
write, or it may simply be a register address that tells
the slave where subsequent data is to be written.
Since data can flow in only one direction as defined by
the R/
W
bit, it is not possible to send a command to a
slave device during a read operation. Before doing a
read operation, it may first be necessary to do a write
operation to tell the slave what sort of read operation to
expect and/or the address from which data is to be read.
3. When all data bytes have been read or written, stop
conditions are established. In WRIT E mode, the master
will pull the data line high during the 10th clock pulse

to assert a ST OP condition. In READ mode, the mas-
ter device will release the SDA line during the low
period before the 9th clock pulse, but the slave device
will not pull it low. T his is known as No Acknowledge.
T he master will then take the data line low during the
low period before the 10th clock pulse, then high dur-
ing the 10th clock pulse to assert a ST OP condition.
