db by register indirection?
the "Devices by Register" section shows you can access a device based on its pin number from a register. Other than alias abuse (alias d db followed by an alias d drn later on, requiring an extra cycle per device), is there another way to do this? --RA2lover (talk) (can't be bothered to find a date, check edit history for that)
while trying to debug a misbehaving network channel load instruction running on a filtration device, apparently you can try accessing an out-of-bounds register and it'll default to db (if the instruction isn't set to throw an OutOfDeviceBounds exception; apparently "l" doesn't at the very least); dr0 with r0 as -1 should do the trick for example. --RA2lover (talk) 16:42, 2 September 2026 (UTC)
nope, within the case of "l" it's ignored and a -1 is returned. "db" maps to int.MaxValue instead, but that goes beyond the number of registers available (18 total; sp is r16, ra is r17) returning a -1 if you try it. --RA2lover (talk) 16:50, 2 September 2026 (UTC)
