Page Write Operation
The 2176-bit memory array is physically realized as
one contiguous array, organized as 17 pages of 16
bytes each. A “Page Write” operation can be per-
formed to any of the GPM or LUT pages. 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 (Vola-
tile)” on page 14.)
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
19). After the receipt of each byte, the X96012
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 20).
The master terminates the loading of Data Bytes by
issuing a STOP condition, which initiates the nonvola-
tile 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, 85h, and 86h 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 21). 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 condition. The
first data byte is written to location 81h, the second to
82h, the third to 83h, and the last one to 84h.
