I'm about to finish my lunch break, sorry if I sound slightly short... 1) is there any pattern or logic to the values placed on the bus during interrupts? I guess an equivalent question is: what realistic options do I have on the Sam for catching and processing interrupts?
2) are there any non-obvious tricks for fast access to a table containing 16bit words, indexed by an 11bit (signed) integer? At the minute I'm essentially doing: [stuff to work out offset into table in hl] ld bc, <address of middle of table - which is aligned to a two-byte boundary> add hl, hl add hl, bc ld e, (hl) inc l ld d, (hl)
