Functional Description
The AK93C45A/55A/65A/75A has 4 instructions such as READ, WRITE, EWEN and EWDS. A valid
instruction consists of a Start Bit (Logic"1"), the appropriate Op Code and the desired memory Address
location.
The CS pin must be brought low for a minimum of 250ns (Tcs) between each instruction when the instruction
is continuously executed.
