Description

The LS7267 has a set of registers associated with each X and Y axis. All X-axis registers have the name prefix X, whereas all Y-axis registers have the prefix Y. Selection of a specific register for Read/Write is made from the decode of the three most significant bits (D7 – D5) of the data bus. The CS input enables the IC for Read/Write. The C/D input selects between control and data information for Read/Write. A complete list of LS7267 registers can be found on the datasheet.
