TIMING CHARACTERISTICS—DSP Mode Enabled (1.8V Logic) (Figure 2)
(DV DD = 1.8V to 2.7V, AGND = DGND = 0, T A = T MIN to T MAX , unless otherwise noted.)
Note 7: In some daisy-chain modes, data is required to be clocked in on one clock edge and the shifted data clocked out on the fol-
Note 8: The falling edge of DSP starts a DSP-type bus cycle, provided that CS is also active low to select the device. DSP active low and

(2.7V) or 50ns (1.8V).
CS active low must overlap by a minimum of 10ns (2.7V) or 20ns (1.8V). CS can be permanently low in this mode of operation.
