The AT93C46E is accessed via a simple and versatile three-wire serial communication inter-
face. Device operation is controlled by seven instructions issued by the host processor. A valid
instruction starts with a rising edge of CS and consists of a start bit (logic “1”) followed by the
appropriate op code and the desired memory address location.
