... During the internal Write cycle, Serial Data (SDA) is disabled internally, and the device does not respond to any requests. If the Write Control input (WC) is driven High, the Write instruction is not executed and the accompanying data bytes are not acknowledged, as shown in 14/41 M24128-BW M24128-BR M24128-BF M24128-DF Figure A13 A12 A11 ...
