This folder does not contain source code for an executable program like most of the other samples.  Rather, this folder contains assembly language source code that demonstrates a few things about code overlays.  This code is intended for reasonably advanced programmers.

This is a demonstration of how overlays can be written. It also contains some useful utility routines for doing DMA to/from arbitrary addresses (see DMA.S) and an overlay loader (see OVERLAY.S).

The main test program is TEST.S; it loads two sets of overlays. The first set of overlays is found in FUNC1.S, the second in FUNC2.S.

Filename Description
dma.s Assembly Source Code
func1.s Assembly Source Code
func2.s Assembly Source Code
overlay.s Assembly Source Code
test.s Assembly Source Code
test.d Puffin debugger script
