Address Only Transaction with a 7-bit Address
When reading data from the slave, the I
the receive interrupt is serviced and the
the I
data byte.
In the situation where software determines if a slave with a 7-bit address is responding
without sending or receiving data, a transaction can be done which only consists of an
address phase.
if a slave with a 7-bit address will acknowledge. As an example, this transaction can be
used after a “write” has been done to a EEPROM to determine when the EEPROM com-
pletes its internal write operation and is once again responding to I
slave does not Acknowledge, the transaction is repeated until the slave does Acknowl-
edge.
Follow the steps below for an address only transaction to a 7-bit addressed slave:
1. Software asserts the IEN bit in the I
2. Software asserts the TXI bit of the I
3. The I
4. Software responds to the TDRE bit by writing a 7-bit Slave address plus write bit (=0)

The NCKI interrupt does not occur in the not acknowledge case because the STOP bit
was set.
