  • For SPI EEPROMs, when executing page write, is it possible to start page write from any address within a page?
    • Page write can be started from any address within a page. After inputting 1 byte (8 bits) of data and the target page address following write instruction when CSB is set to 'L', if data continues to be input while CSB remains at 'L' (doesn't return to 'H'), the address will be internally incremented with data in consecutive addresses written to the register (the address returns to the beginning once it reaches the end of the page, overwriting the previous data). When CSB returns to 'H' operation shifts to the internal write cycle of the EEPROM. Please refer to the datasheet for more information.
