Figure 36. READ ARRAY SEQUENCE (Parallel)
Notes :
1. 1st Byte='03h'
2. 2nd Byte=Address 1(AD1), AD23=bit7, AD22=bit6, AD21=bit5, AD20=bit4,....AD16=bit0.
3. 3rd Byte=Address 2(AD2), AD15=bit7, AD14=bit6, AD13=bit5, AD12=bit4,....AD8=bit0.
4. 4th Byte=Address 3(AD3), AD7=bit7, AD6=bit6, ....AD0=bit0.
5. From Byte 5, PO7-0 Would Output Array Data.
6. Under parallel mode, the fastest access clock freq. will be changed to 6MHz(SCLK pin clock freq.).
7. To read array in parallel mode requires a parallel mode command (55h) before the read command.
