Yes, I did mean that this firmware would appear to stop and wouldn't proceed any further - rather than the endless-loop jumping much further-back to re-attempt writing / reading of the RAM (So meaning those lines could be probed with 'scope etc).
As the 6502 uP lacks HALT (until Interrupt) instruction of the Z80 etc. (or any Sleep modes of more modern uC's).
