○Internal address increment
○Write protect (WP) terminal
・Write protect (WP) function
When WP terminal is set Vcc (H level), data rewrite of all address 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.
Page write mode (in the case of BR24S16-W)
For example, when it is started from address 0Eh, therefore, increment is made as below,
0Eh→0Fh→00h→01h・・・, which please note.
* 0Eh・・・16 in hexadecimal, therefore, 00001110 becomes a binary number.
