INT bit : Indicator for DataRAM’s Status (Ready=1, Busy=0)
RDY: Indicator for Latency of Sync Burst Block Read
Burst Length: 4, 8, 16, 32, 1K Word Synchronous Burst Block Read are available.
A1-1 ~ A1-N: Address where each burst data initiates, and this may differ for different settings of BSA and BL.
N can be calculated by 1024w / BL.
Therefore, for above case, BSA=0200h and BL=8word. So that N=128, A1-1=0200h, A1-2=0208h ... A1-128=05F8h.
WE
must be set high throughout the operation.
