GENERAL DESCRIPTION
The device features a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). Serial access to the device is enabled by CS# input.
When it is in Dual Output read mode, the SI and SO pins become SIO0 and SIO1 pins for data output.
The device provides sequential read operation on the whole chip.
