IL
(loading a new address) or
CNTEN
= V

(advancing the address), i.e.
ADS

and
CNTEN

the data output remains constant for subsequent clocks.

NOTES:
1. Output state (High, Low, or High-impedance) is determned by the previous cycle control signals.

3. Addresses do not have to be accessed sequentially since
ADS
= V
IL
constantly loads the address on the rising edge of the CLK; numbers are for reference use
only.
4. This timng does not meet requirements for fastest speed grade. This waveformindicates how logically it could be done if timng so allows.
