Notes:
1.
2.
Internal burst counter is fixed as 2-bit linear (i.e., when first address is A0+0, next internal burst address is A0+1.
“READ” refers to read active status with R = Low, “READ” refers to read inactive status with R = High. The same is
true for “WRITE” and “WRITE”.
Read and write state machine can be active simultaneously.
State machine control timing sequence is controlled by K.
