○Internal address increment
○Write protect (WP) terminal
Page write mode (in the case of BR24L02-W)
For example, when it is started from address 06h,therefore, increment is made as below,
06h → 07h → 00h → 01h ---, which please note.
＊
・Write protect (WP) function
When WP terminal is set Vcc (H level), data rewrite of all addresses is prohibited. When it is set GND (L level), data
rewrite of all address is enabled. Be sure to connect this terminal to Vcc or GND, or control it to H level or L level.
Do not use it open.
At extremely low voltage at power ON / OFF, by setting the WP terminal 'H', mistake write can be prevented.
During tWR, set the WP terminal always to 'L'. If it is set 'H', write is forcibly terminated.
06h･･･06 in hexadecimal, therefore, 00000110 becomes a binary number.
