NOTES:
1. Timing is illustrated and referenced with respect to W-RN and CEN inputs. Internal read and write activities are controlled by the Sclk as it
generates the several “C” timing as shown in the timing diagrams.
2. The minimum time before the rising edge of the next C2 time to stop the next bus cycle. CEN must return high after midpoint of C4 time and
before the C2 time of the next cycle.
3. Delay is from cEN high in Async mode to IRQN inactive, from end of C4 to IRQN inactive in sync mode.
4. The minimum frequency values are not tested, but are guaranteed by design.
5. 1MHz specification is for crystal operation.
