Power-Up and Power-Down
Input Signal Overshoot
During DC conditions, input or I/O signals should remain equal to or between V
transitions, inputs or I/Os may overshoot V

A simple pull-up resistor (generally of the order of 100 k) on Chip Select (CS#) can usually be used to insure
safe and proper power-up and power-down.
