    PC=0x96 has no relation to any lines in your source code. So, no, there's no point in looking at line 150. Line 150 is completely irrelevant here. And where exactly in the manual did you read that 0x0024 is RETI? Commented May 11, 2019 at 2:05

    Where's the program? Errors like that might easily be caused by out-of-bounds local array modification. Stack damage smashes the stored function's return address, making it "return" to a completely wrong location (e.g. 0x96), hitting "invalid instructions" stored there. Commented May 11, 2019 at 2:52

    PC=0x96 means the program counter is pointing to that memory location and it is trying to execute the instruction at that location ..... the last picture shows code at 0x1ab4 Commented May 11, 2019 at 2:54

    I have the same problem. Would you tell me please, if you have solved the problem, and how? Commented Dec 10, 2020 at 10:39
