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.
