These devices are fully compatible with the SPI protocol.
All instructions, addresses and input data bytes are shifted in to the device, most significant
bit first. The Serial Data input (D) is sampled on the first rising edge of the Serial Clock (C)
after Chip Select (S) goes low.
All output data bytes are shifted out of the device, most significant bit first. The Serial Data
output (Q) is latched on the first falling edge of the Serial Clock (C) after the instruction (such
as the Read from Memory Array and Read Status Register instructions) have been clocked
into the device.

others being high impedance.

Only one memory device is selected at a time, so only one memory device drives the Serial
Data output (Q) line at a time, the other memory devices are high impedance.
The pull-up resistor R (represented in
Bus Master leaves the S line in the high impedance state.
In applications where the Bus Master may be in a state where all input/output SPI buses are
high impedance at the same time (for example, if the Bus Master is reset during the
transmission of an instruction), the clock line (C) must be connected to an external pull-
down resistor so that, if all inputs/outputs become high impedance, the C line is pulled low
(while the S line is pulled high): this ensures that S and C do not become high at the same
time, and so, that the t
