3. The "Internal Address" is equal to the "External Address" when
ADS
= V
IL
and equals the counter output when
ADS
= V
IH
.
4. No dead cycle exists during
REPEAT
operation. A READ or WRITE cycle may be coincidental with the counter
REPEAT
cycle: Address loaded by last valid
ADS
load will be accessed. For more information on
REPEAT
function refer to Truth Table II.
5.
CNTEN

advances Internal Address from‘An to ‘An +1’. The transition shown indicates the time required for the counter to advance. The ‘An +1’Address is
written to during this cycle.
6. The counter includes bank address and internal address. The counter will advance across bank boundaries. For example, if the counter is in Bank 0, at address
FFFh, and is advanced one location, it will move to address 0h in Bank 1. By the same token, the counter at FFFh in Bank 63 will advance to 0h in Bank 0.
7. For Pipelined Mode user should add 1 cycle latency for outputs as per timng waveformof read cycle for pipelined operations.
