Still doesn't match the example. And the example will fail when it does.
Noted, will change it.

reg-names?
should be -const: ebunand instead added description with register
name , will keep "-const: ebunand ..etc"

Not documented or should be dropped.
Yes, will drop it.

Not documented. And needs a space after the ','.
Good catch, Thanks

Should be removed?
sure, will remove it
