Page Write Operation
The 2176-bit memory array is physically realized as
one contiguous array, organized as 17 pages of 16
bytes each. In order to perform a Page Write operation
to the memory array, the Write Enable Latch (WEL) bit
in Control register 6 must first be set (See “WEL: Write
Enable Latch (Volatile)” on page 7.)
A Page Write operation is initiated in the same manner
as the byte write operation; but instead of terminating
the write cycle after the first data byte is transferred,
the master can transmit up to 16 bytes (See Figure
16). After the receipt of each byte, the X9530 responds
with an ACK, and the internal byte address counter is
incremented by one. The page address remains
constant. When the counter reaches the end of the
page, it “rolls over” and goes back to the first byte of
the same page.
For example, if the master writes 12 bytes to a 16-byte
page starting at location 11 (decimal), the first 5 bytes
are written to locations 11 through 15, while the last 7
bytes are written to locations 0 through 6 within that
page. Afterwards, the address counter would point to
location 7. If the master supplies more than 16 bytes of
data, then new data overwrites the previous data, one
byte at a time (See Figure 17).
The master terminates the loading of Data Bytes by
issuing a STOP condition, which initiates the
nonvolatile write cycle. As with the Byte Write
operation, all inputs are disabled until completion of the
internal write cycle.
A Page Write operation cannot be performed on the
page at locations 80h through 8Fh. Next section
describes the special cases within that page.
A Page Write operation starting with byte address FFh,
accesses the page between locations 100h and 10Fh.
The first data byte of such operation is written to
location 100h.
Writing to Control Registers
The byte at location 80h, and bytes at locations 85h
through 8Fh are written using Byte Write operations.
They cannot be written using a Page Write operation.
Control bytes 1 through 4, at locations 81h through 84h
respectively, are written during a single operation (See
Figure 18). The sequence must be: a START, followed
by a Slave Address byte, with the R/W bit equal to “0”,
followed by 81h as the Address Byte, and then
followed by exactly four Data Bytes, and a STOP
