Serial Interface MASTER: The device that generates the serial clock. Description SLAVE: Because the Serial Clock pin (SCK) is always an input, the AT25080/160/320/640 always operates as a slave. TRANSMITTER/RECEIVER: The AT25080/160/320/640 has separate pins designated for data transmission (SO) ...

... WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select one of four levels of protection. The AT25080/160/320/640 is divided into four array segments. One quarter (1/4), one half (1/2), or all of the memory segments can be protected. Any of the data within any selected segment will therefore be READ only. The block write protection levels and corresponding status register control bits are shown in Table 4 ...

... First, the device must be write enabled via the Write Enable (WREN) Instruction. Then a Write (WRITE) Instruction may be executed. Also, the address of the memory location( programmed must be outside the protected address field location selected by the Block Write Protection Level. During an internal write cycle, all commands will be ignored except the RDSR instruction ...
