Has anyone used a part like this? I thought the 8051 architecture was limited to 64k code space, but I see there are some with a larger flash/code part. How is that handled by SDCC? Does it care? I mean if I exceed the 64k boundary of the original design will I have some error to ignore - or are there special instructions required to address above 64k code?
Look in the manual and search for bankswitching.
Looks like its a bit fragile.
