ELECTRICAL CHARACTERISTICS (continued)
(V
Note 1: All parameters tested at T
Note 2: Timing specifications guaranteed by design.
Note 3: The serial interface resets when SCLK is low for more than t
Note 4: A transition must internally provide at least a hold time to bridge the undefined region (300ns max) of SCLK’s falling edge.
