2. CE 0 , BE n = V IL ; CE 1 = V IH .
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. A 19 must be in the appropriate state when using the REPEAT
function to guarantee the correct address location is loaded.
5. CNTEN = V IL 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. For Pipelined Mode user should add 1 cycle latency for outputs as per timing waveform of read cycle for pipelined operations.
7. Address A 19 must be managed as part of a full depth counter implementation using the IDT70T3509M. For physical addresses 00000 H through 7FFFF H the
value of a A 19 is 0, while for physical addresses 80000 H through FFFFF H the value of A 19 is 1. The user needs to keep track of the device counter and make
sure that A 19 is actively driven from 0-to-1 or 1-to-0 and held as needed at the appropriate address boundaries for full depth counter operation. As shown this
transition reflects An = 7FFFF H or FFFFF H .
