NOTES:
1. Write is defined as either any SBx and SW low or SGW is low. Chip Enable is defined as SE1 low, SE2 high and SE3 low whenever ADSP
or ADSC is asserted.
2. All read and write cycle timings are referenced from K or G.
3. G is a don’t care after write cycle begins. To prevent bus contention, G should be negated prior to start of write cycle.
4. This parameter is sampled and not 100% tested.
5. Measured at ± 200 mV from steady state.
