Technical Note  
Bidirectional mode command  
Byte Write  
When the Master generates a STOP condition, the BR24C21/F/FJ/FV begins the internal write cycle to the nonvolatile array.

Fig.10 Byte Write Cycle Timing  
Page Write  
If the Master transmits the next data instead of generating a STOP condition during the byte write cycle, the  
BR24C21/F/FJ/FV transfers from byte write function to page write function. After receipt of each word, the three lower  
order address bits are internally incremented by one, while the high order four bits of the word address remains  
constant.  
If the master transmits more than eight words, prior to generating the STOP condition, the address counter will “roll  
over,” and the previous transmitted data will be overwritten.

Fig.11 Page Write Cycle Timing  
Current Read  
The BR24C21/F/FJ/FV contains an internal address counter which maintains the address of the last word accessed,  
incremented by one. If the last accessed address is address “n” in a Read operation, the next Read operation will  
access data from address “n+1” and increment the current address counter. If the last accessed address is address  
”n” in a Write operation, the next Read operation will access data from address “n”. If the Master does not transfer an  
Acknowledge, but does generate a STOP condition, the current address read operation will only provide a single byte of  
data. At this point, the device discontinues transmission.
