NOTES:
1. Write applies to all SBx, SW, and SGW signals when the chip is selected and ADSP high.
2. Chip Enable applies to all SE1, SE2 and SE3 signals whenever ADSP or ADSC is asserted.
3. All read and write cycle timings are referenced from K or G.
4. G is a don’t care after write cycle begins. To prevent bus contention, G should be negated prior to start of write cycle.
5. Tested per AC Test Load.
6. Measured at
±
200 mV from steady state. Tested per High–Z Test Load.
7. This parameter is sampled and is not 100% tested.
