Extra Explanation portSAVE_CONTEXT() ?Posted by Steven on August 26, 2010 Hello all, I have 2 questions, hope to hear from you. 1. Am I correct in saying that if you do: "MOVFFWREG, PREINC1" that you save the WREG on the first not used part of the FSR? if not, how do I have to see it? 2. On the section about "/* Store the .tempdata and MATH_DATA areas as described above. */" there are 13 times: MOVFFPOSTINC0, PREINC1 .....1. can't we write the code in a way that we use portCOMPILER_MANAGED_MEMORY_SIZE so it's more generic? .....2. I dont understand the code fully: for postinc0 : so you copy the value of fsr, then you increase, for preinc1: you increment again and save value? is it that way because of 16bit? then i understand.. thanks in advance for help!!!
