Good question. I hadn't thought much about the eeprom addresses on the
small PICs. I suppose a quick fix would be to raise the max address to
0x217F for that MCU (and similarly for others), but that will defeat
the purpose for those MCUs because there won't be a warning when you
first go over address 0x2000. It looks like ultimately we'll also need
the eeprom bounds separately in gpasm.
I don't know offhand... are there any MCU's with more than 2
non-consecutive ROM address ranges? This bounds checking for absolute
mode may be much stickier than I thought...
