7.10.3   Read operations
7.10.3.1   Current address read
In Standby mode, the SE97B internal address counter points to the data byte immediately
following the last byte accessed by a previous operation. If the previous byte was the last
byte in memory, then the address counter will point to the first memory byte, and so on. If
the SE97B decodes a slave address with a 1 in the R/W
 bit position (Figure 15
), it will
issue an Acknowledge in the ninth clock cycle and will then transmit the data byte being
pointed at by the address counter. The master can then stop further transmission by
issuing a No Acknowledge on the ninth bit then followed by a STOP condition.
 
7.10.3.2   Selective read
The read operation can also be started at an address different from the one stored in the
address counter. The address counter can be initialized by performing a dummy write
operation (Figure 16
). The START condition is followed by the slave address (with the
R/W
 bit set to 0) and the desired byte address. Instead of following-up with data, the
master then issues a second START, followed by the Current Address Read sequence,
as described in Section 7.10.3.1
.
