24AAXX/24LCXX/24FCXX
8.3 Sequential Read
Sequential reads are initiated in the same way as a
random read except that after the 24XX transmits the
first data byte, the master issues an acknowledge as
opposed to the Stop condition used in a random read.
This acknowledge directs the 24XX to transmit the next
sequentially addressed data byte (Figure 8-4). Follow-
ing the final byte transmitted to the master, the master
will NOT generate an acknowledge but will generate a
Stop condition. To provide sequential reads, the 24XX
contains an internal Address Pointer which is incre-
mented by one at the completion of each operation.
This Address Pointer allows the entire memory con-
tents to be serially read during one operation. If the last
address byte in the array is acknowledged, the Address
Pointer will roll over to address 0x00.
