READ OPERATIONS
Immediate Address Read
In standby mode, the CAT24C03 internal address counter
points to the data byte immediately following the last byte
accessed by a previous operation. If that ‘previous’ byte
was the last byte in memory, then the address counter
will point to the 1
st
memory byte, etc.
When, following a START, the CAT24C03 is presented
with a Slave address containing a ‘1’ in the R/W bit
position (Figure 8), it will acknowledge (ACK) in the 9
th
clock cycle, and will then transmit data being pointed
at by the internal address counter. The Master can stop
further transmission by issuing a NoACK, followed by a
STOP condition.
Selective Read
The Read operation can also be started at an address
different from the one stored in the internal address coun-
ter. The address counter can be initialized by performing
a ‘dummy’ Write operation (Figure 9). Here the START
is followed by the Slave address (with the R/W bit set
to ‘0’) and the desired byte address. Instead of follow-
ing up with data, the Master then issues a 2
nd
START,
followed by the ‘Immediate Address Read’ sequence,
as described earlier.
Sequential Read
If the Master acknowledges the 1
st
data byte transmitted
by the CAT24C03, then the device will continue trans-
mitting as long as each data byte is acknowledged by
the Master (Figure 10). If the end of memory is reached
during sequential Read, then the address counter will
‘wrap-around’ to the beginning of memory, etc. Sequential
Read works with either ‘Immediate Address Read’ or
‘Selective Read’, the only difference being the starting
byte address.
