8. 关于24C02的页写入模式，我察看了一个24C02的数据手册对页写模式的摘写下来：Page Write. For the Page Writemode, the MODEpin must be at VIL. The Page Write mode allows upto 8 bytes to bewritten in a single write cycle,providedthat they are all located in the same ’row’in the memory: that is the 5 mostsignificant mem-ory address bits (A7-A3) are the same. The mastersends from oneup to 8 bytes of data, which areeach acknowledged by the memory. After eachbyteis transfered, the internal byte address counter(3 least significant bits only)is incremented. Thetransfer is terminated by the master generating aSTOPcondition. Care must be taken to avoid ad-dress counter ’roll-over’ which couldresult in databeing overwritten. Note that, for any write mode,the generationby the master of the STOP conditionstarts the internal memory program cycle.All inputsare disabled until the completion of this cycle andthe memory willnot respond to any request.
Sequential Read. This mode can be initiated witheither a Current Address Read or a Random Ad-dress Read. However, in this case the masterDOES acknowledge the data byte output and thememory continues to output the next byte in se-quence. To terminate the stream of bytes, themaster must NOT acknowledge the last byte out-put, but MUST generate a STOP condition. Theoutput data is from consecutive byte addresses,with the internal byte address counter automat-ically incremented after each byte output. After acount of the last memory address, the addresscounter will ’roll- over’ and the memory will continueto output data.
