Figure 7. Write Mode Sequences with WC=1 (data write inhibited)

Write Operations

Following a Start condition the bus master sends

a Device Select Code with the Read/Write bit

(RW) reset to 0. The device acknowledges this, as

shown in Figure 8., and waits for two address

bytes. The device responds to each address byte

with an acknowledge bit, and then waits for the

data byte.

Writing to the memory may be inhibited if Write

Control (WC) is driven High. Any Write instruction

with Write Control (WC) driven High (during a pe-

riod of time from the Start condition until the end of

the two address bytes) will not modify the memory

contents, and the accompanying data bytes are

not acknowledged, as shown in Figure 7..

Each data byte in the memory has a 16-bit (two

byte wide) address. The Most Significant Byte (Ta-

ble 4.) is sent first, followed by the Least Signifi-

cant Byte (Table 5.). Bits b15 to b0 form the

address of the byte in memory.

When the bus master generates a Stop condition

immediately after the Ack bit (in the “10th bit” time

slot), either at the end of a Byte Write or a Page

Write, the internal Write cycle is triggered. A Stop

condition at any other time slot does not trigger the

internal Write cycle.

After the Stop condition, the delay tW, and the suc-

cessful completion of a Write operation, the de-

vice’s internal address counter is incremented

automatically, to point to the next byte address af-

ter the last one that was modified.

During the internal Write cycle, Serial Data (SDA)

is disabled internally, and the device does not re-

spond to any requests.

Byte Write

After the Device Select code and the address

bytes, the bus master sends one data byte. If the

addressed location is Write-protected, by Write

Control (WC) being driven High, the device replies

with NoAck, and the location is not modified. If, in-

stead, the addressed location is not Write-protect-

ed, the device replies with Ack. The bus master

terminates the transfer by generating a Stop con-

dition, as shown in Figure 8..
