The status of software write protection can be determined using these instructions:
The controller issues a Read SWP command. If Software Write Protection has not been set, the device replies to the data byte with an Ack. If Soft-
The controller issues a Read PSWP command. If Permanent Software Write Protection has not been set, the device replies to the data byte with
Following a Start condition the bus master sends a Device Select Code with the R/W# bit reset to 0. The device acknowledges this, as shown in
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
During the internal Write cycle, Serial Data (SDA) and Serial Clock (SCL) are ignored, and the device does not respond to any requests.
