Although natively working with 16-bit words (14-bit pairs of instructions or data), CPU7 is also supposed to handle "raw" unformatted data in 8-bit, 16-bit, or 32-bit format. As an example that could be a hardware register, video memory, or anything which is not part of CPU7.

As a small coding exercise to test the flavour of the CPU7 assembler, here is the well known "bubble sort" of an area of unformatted bytes.
