Architectural Features
- The RS08 core does not manage a stack. During subroutine calls, it preserves a return address in a Shadow Program Counter register. If a subroutine in turn calls another subroutine, it can preserve the return address in a local variable, call subroutines as necessary, and restore the saved address just before returning.
- The core's Status register has Carry and Zero flag bits. Overflow and Negative, usually found in other cores, are not present.

Famous quotes containing the word features:
““It looks as if
Some pallid thing had squashed its features flat
And its eyes shut with overeagerness
To see what people found so interesting
In one another, and had gone to sleep
Of its own stupid lack of understanding,
Or broken its white neck of mushroom stuff
Short off, and died against the windowpane.””
—Robert Frost (1874–1963)
