Sequential Read
Sequential reads are initiated in the same way as a ran-
dom read except that after the 24LC32A transmits the
rst data byte, the master issues an acknowledge as
opposed to the stop condition used in a random read.
This acknowledge directs the 24LC32A to transmit the
next sequentially addressed 8 bit word (see Figure 8-
3). Following the nal byte transmitted to the master,
the master will NOT generate an acknowledge but will
generate a stop condition.
To provide sequential reads the 24LC32A contains an
internal address pointer which is incremented by one at
the completion of each operation. This address pointer
allows the entire memory contents to be serially read
during one operation. The internal address pointer will
automatically roll over from address 0FFF to address
000 if the master acknowledges the byte received from
the array address 0FFF.
