Write Operations (Continued)
Current Address Read
The AM24LC16 contains an address counter that
maintains the address of the last accessed word,
internally incremented by one. Therefore if the
previous access (either a read or write operation )
was to address n, the next current address read
operation would access data from address n + 1.
Upon receipt of the slave address with R/W bit set to
one, the AM24LC16 issues an acknowledge and
transmits the eight bit data word . The master will
not acknowledge the transfer but does generate a
stop condition and the AM24LC16 discontinues
transmission. (Shown in Figure 6)
Random Read
Random read operations allow the master to access
any memory location in a random manner. To
perform this type of read operation, first the word
address must be set. This is done by sending the
word address to the AM24LC16 as part of a write
operation. After the word address is sent, the master
generates
a
start
condition
following
the
acknowledge. This terminates the write operation,
but not before the internal address pointer is set.
Then the master issues the control byte again but
with R/W bit set to a one. The AM24LC16 will then
issue an acknowledge and transmit the eight bit data
word. The master will not acknowledge the transfer
but does generate a stop condition and the
AM24LC16 discontinues transmission. (Shown in
Figure 7)
Sequential Read
Sequential read is initiated in the same way as a
random read except that after the AM24LC16
transmits the first data byte, the master issues an
acknowledge as opposed to a stop condition in a
random read. This directs the AM24LC16 to transmit
the next sequentially addressed 8 bit byte (Shown in
Figure
8).
To
provide
sequential
read
the
AM24LC16 contains an internal address pointer
which is incremented by one at the completion of
each operation.
Noise Protection
The SCL and SDA inputs have filter circuits which
suppress noise spikes to assure proper device
operation even on a noisy bus.
