so far, I've been
writing two- or three- instruction loops which have the picked bit set in all

Here is a trick for you.
If the MMU is off, you can consider the PAR registers as just plain ram.
And it is big enough to fit small programs in. So write your small test
programs there, and run them.
No need to setup memory mapping and all kind of things. :-)
