relocate Interrupt vector start address My approach to this sort of problem was to partition the Flash into N+1 sections. (Where N is the number of possible applications which you want to be able to fall back on at any...

Port.Pin as function parameter. To be absolutely clear, skeeve's response implies that you can use pass-by-value semantics only.
Pass-by-reference semantics (and, therefore, the ability for the callee to modify...

(From memory)
The RETI instruction causes the CPU to re-enable interrupts. For classic 8-bit AVRs, that...

AT32UC3C0256C flashing problem Just a guess, but I note that your hex file contains a suspicious entry right at the top: 2 bytes of data at address 0x0000DE00. Your linker script suggests it is for something...

Using the MSU's CRC32 engine Oh, I know *how* to do a CRC. But I was hoping to use hardware acceleration if possible. Primarily for speed, but also because I have a philosophy of not doing something in...
