Chipselect High-to-Low transitions are invoking commands, which are transmitted through data lines during next following eight CLK pulses, after the command transmission, further CLK pulses are used to transfer data, the data transfer ends at chipselect Low-to-High transition. Data should be stable during CLK=LOW period throughout CLK rising edge.

Note: Supply Pins (1,8,17) are slightly longer than other pins.
