List of numbers of page write
The above numbers are maximum bytes for respective types.
Any bytes below these can be written.
In the case BR24G32-3A, 1 page=32bytes, but the page
write cycle time is 5ms at maximum for 32byte bulk write.
It does not stand 5ms at maximum × 32byte=160ms(Max.)
Page write mode
・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.
In the case of use it as an ROM, it is recommended to connect it to pull up or Vcc.
At extremely low voltage at power ON / OFF, by setting the WP terminal 'H', mistake write can be prevented.

therefore, increment is made as below,

※1Eh･･･1E in hexadecimal, therefore, 00011110 becomes a
binary number.
