In addition to the registers listed above the CL-GD542X extends the functionality of
several of the standard VGA registers. While operating in standard VGA modes these
extensions are inactive, and the registers comply with the VGA standard.
Note

uses a different set of extension registers. Refer to Appendix B for further information.
