Why do you keep talking about SBCs?  We're talking about microcontrollers, =
in particular 32-bit devices that run at 10s to 100s of MHz and have tens o=
f kilobytes to a few megabytes of program memory, and less than that of RAM=
.  Far from being an SBC, such boards may be as simple as the processor, a =
crystal and the necessary bypass caps.  Everything else is header pins.

And these micros continue to have those memory-mapped hardware registers, a=
nd those of us who program these chips deal with those registers all the ti=
me.
