10 / 18 page DATA PROTECTION AND PROTOCOL SAFETY – All inputs are protected against noise, see Table 6. – Non valid S and HOLD transitions are not taken into account. – S must come high at the proper clock count in order to start a non-volatile write cycle (in the memory array or in the status register), that is the Chip Select S mustrise during the clock pulse following the introduction of a multiple of 8 bits. – Access to the memory array during non-volatile programming cycle is ignored; however, the pro- gramming cycle continues. – After any of the operations WREN, WRDI, RDSR is completed, the chip enters a wait state and waits for a deselect. – The write enable latch is reset upon power-up. – The write enable latch is reset when W is brought low. INITIAL DELIVERY STATE The device is delivered with the memory array in a fully erased state (all data set at all ”1’s” or FFh). The block protect bits are initialized to 00.
