Device Bus Operation
Notes:
1.
For High/Low configuration, either the first or last sector was protected if #WP/ACC=VIL.
For Top/Bottom Boot configuration, either the top or bottom two sectors are 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 A20 to A0. In Byte Mode (Byte#=VIL), the addresses are A20 to A-1
(DQ15),.
