Notes
36. Parameter is not tested and values suggested are for system design consideration only in preventing the occurrence of double pulsing.
37. Enable time required for SO. Pull-up resistor = 10 kΩ.
38. Disable time required for SO. Pull-up resistor = 10 kΩ.
39. Time required to obtain valid data out of SO following the falling edge of SCLK.
