The first or last sector was protected if #WP/ACC=VIL. 2. When #WP/ACC = VIH, the protection conditions of the outmost sector depends on previous protection conditions. Refer to the enhanced protect feature. 3. DQ[15:0] are input (DIN) or output (DOUT) pins according to the requests of instruction sequence, sector protection, or data polling algorithm. 4. In Word Mode (#BYTE=VIH), the addresses are A22 to A0. In Byte Mode (#BYTE=VIL), the addresses are A22 to A- 1 (DQ15),.
