Note 1:
High impedance is measured by pulling to mid-rail with R
L
= 1K/1K potential divider, with timing corrected to cancel time taken
to discharge C
L
.

Note: There must be a minimum of 30ns between CPU accesses, to allow the MT90869 device to recognize the
accesses as separate (i.e. a minimum of 30ns must separate the de-assertion of DTA_b (to high) and the assertion
of CS_b and/or DS_b (to initiate the next access).
