... RAM buffer until a STOP condition is detected. This STOP condi- tion initiates the internal programming cycle. The RAM buffer is 2 bytes for the 24C01A/02A and 8 bytes for the 24C04A. If more than 2 bytes are transmitted by the master to the 24C01A/02A, the device will not acknowl- edge the data transfer and the sequence will be aborted ...

... WP pin, the 24C02A/04A will not generate an acknowledge after the first byte of data has been received, and thus the program cycle will not be started when the STOP condition is asserted. Polarity of the WP pin has no effect on the 24C01A. 9.0 READ MODE This mode illustrates master device reading data from the 24C01A/02A/04A ...
