WPB
WPB must be open or pulled down normally. When Flash is erased or programmed, WPB must be held High.
SDA, SCL, EXCLK, and WPB will tolerate 3 V input at the time of power off.
Power must remain applied to the device during flash access in order to prevent unintentional rewriting of the flash
memory.
Data in flash memory may be rewritten unintentionally if the specified power sequencing techniques are not kept.
