Timing Waveform of Write with Address Counter Advance
(Flow-Through or Pipelined Outputs)
NOTES:
1. CE
2. CE
3. The "Internal Address" is equal to the "External Address" when ADS = V
4. Addresses do not have to be accessed sequentially since ADS = V
5. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals.
6. No dead cycle exists during counter reset. A READ or WRITE cycle may be coincidental with the counter reset cycle. ADDR
7. CNTEN = V
