Greetings, For reasons known only to MicroChip, the 12 & 14 bit cores count the code area in words, whereas the 16 bit cores count it in bytes (though every instruction is two bytes, or one word).
Prior to jal 2.4l-beta, this was no being handled correctly. The code generation was correct, but the assembly output did not match mpasm. This ended up causing not only confusion but a problem when generating `asm goto n' -- the result ended up being `goto 2n'. This has been fixed, but the generated device files for the 16 bit cores may not be correct. I've not checked. From section 5.1 of ``PIC18F2420/2520/4420/4520 Data Sheet'', we see: ``The PIC18F2420 and PIC18F4420 each have 16 Kbytes of Flash memory and can store up to 8,192 single-word instructions. The PIC18F2520 and PIC18F4520 each have 32 Kbytes of Flash memory and can store up to 16,384 single-word instructions.'' The means, for these chips we need: pragma code 16384 and pragma code 32768 (the total number of bytes available, *not* the total number of words). Hopefully this is clear. --kyle --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "jallib" group.
