Register Function: This register is used for disabling / enabling each abnormal diagnosis function
as necessary. Relation between the diagnosis function and EBDIS is as following. Each bit have its
function, and “1” means DISABLE. The register value is duplicated from corresponding memory
after power on or, when the mode transferred to "Normal Mode" from “User Mode”.
