WRITE OPERATION

Page Write
6.1
Byte Write
The write control byte, word address and the first data
byte are transmitted to the 24XX16 in the same way as
Following the Start condition from the master, the
device code (4 bits), the block address (3 bits) and the
R/W bit, which is a logic-low, is placed onto the bus by
the master transmitter. This indicates to the addressed
slave receiver that a byte with a word address will
follow once it has generated an Acknowledge bit during
the ninth clock cycle. Therefore, the next byte transmit-
ted by the master is the word address and will be
written into the Address Pointer of the 24XX16. After
receiving another Acknowledge signal from the
24XX16, the master device will transmit the data word
to be written into the addressed memory location. The
24XX16 acknowledges again and the master
generates a Stop condition. This initiates the internal
in a byte write. However, instead of generating a Stop
condition, the master transmits up to 16 data bytes to
the 24XX16, which are temporarily stored in the on-
chip page buffer and will be written into memory once
the master has transmitted a Stop condition. Upon
receipt of each word, the four lower-order Address
Pointer bits are internally incremented by ‘ 1 ’. The
higher-order 7 bits of the word address remain
constant. If the master should transmit more than 16
bytes prior to generating the Stop condition, the
address counter will roll over and the previously
received data will be overwritten. As with the byte write
operation, once the Stop condition is received an
internal write cycle will begin (Figure 6-2).
write cycle and, during this time, the 24XX16 will not
generate Acknowledge signals (Figure 6-1).
Note:
6.3
Page write operations are limited to writing
bytes within a single physical page,
regardless of the number of bytes
actually being written. Physical page
boundaries start at addresses that are
integer multiples of the page buffer size (or
‘page-size’) and end at addresses that are
integer multiples of [page size – 1]. If a
page write command attempts to write
across a physical page boundary, the
result is that the data wraps around to the
beginning of the current page (overwriting
data previously stored there), instead of
being written to the next page, as might be
expected. It is therefore necessary for the
application software to prevent page write
operations that would attempt to cross a
page boundary.
Write Protection
The WP pin allows the user to write-protect the entire
array (000-7FF) when the pin is tied to V CC . If tied to
V SS the write protection is disabled.
