STATE DIAGRAM

Notes: 1. Internal burst counter is fixed as 2-bit linear, i.e. when first address is A0+0, next internal burst address is A0+1.

2. "READ" refers to read active status with R=Low, "READ" refers to read inactive status with R=high. "WRITE" and "WRITE" are the same case.

3. Read and write state machine can be active simultaneously.

4. State machine control timing sequence is controlled by K.
