Acknowledgment Hold Time
High Impedance is measured by pulling to the appropriate rail with R
C
There must be a minimum of 30ns between CPU accesses, to allow the device to recognize the accesses as separate (i.e., a
minimum of 30ns must separate the de-assertion of DTA (to high) and the assertion of CS and/or DS to initiate the next
access).
