... By setting WP "HIGH" in the area, write can be cancelled. When it is set WP = "HIGH" during tWR, write is forcibly ended, and data of address under access is not guaranteed, therefore write it once again Start condition 2/16 Memory cell characteristics (Ta = 25˚C, Vcc = 1.8 ~ 5.5V) Unit Parameter V Min. *2 ...

... Fig.39 Page write cycle (BR24L32/64-W) Data is written to the address designated by word address (n-th address). By issuing stop bit after 8bit data input, write to memory cell inside starts. When internal write is started, command is not accepted for tWR (5ms at maximum). By page write cycle, the following can be written in bulk bytes (BR24L01A-W, BR24L02-W) And when data of the maximum bytes or higher is sent, data from the first byte is overwritten. (Refer to " ...
