Note: 1 Data Hold Time T1 depends on SCLK high time and Max Data Hold time. It is Always 3-8ns
before SCLK pulse falling edge
2 The input signal rise and fall times must be within 10ns.
3 Every timing is specified on the basis of 30% and 70% of VDDI.
4 T_amb = -40 to 85°C, unless otherwise specified.
