However, I am now unable to debug this project--it complains that it can't find source code at 0xfffffffe and then crashes, even after I set the Program Counter to the function "ResetISR" in the Debug Configuration [PEMicro's "Set PC (absolute hex address or symbol)"]. ...

Overall Configuration of the CPU: Program Counter Call an execution instruction The program counter (PC) is a register that manages the memory address of the instruction to be executed next. The address specified by the PC will be + n (+1 for a 1-word instruction...
Acall stackis a series of program counter addresses (PCs) representing instructions from within the program. The first PC, called theleaf PC, is at the bottom of the stack, and is the address of the next instruction to be executed. The next PC is the address of the call to the functio...
and thus can't determine the size of that function's stack frame. This means that GDB may be unable to access that stack frame, or the frames below it. This problem is most likely caused by an invalid program counter or stack pointer. ...
Program counter. Also known as an instruction pointer, the program counter plays an organizational role. It keeps track of where a computer is in its program sequence. Stack. A stack is a data structure that stores information about the active subroutines of a computer program. It is used as...
By default the stack is located in the 256-byte IDATA space of internal data memory. The IDATA stack is referenced solely by the 8-bit Stack Pointer (SP: 81H). Setting the XSTK bit in AUXR1 (see Table 5-6) enables the extended stack. The extended stack resides in the EDATA space ...
