now shows a green arrow pointing to the line of code at address 0, the reset
location.
The instruction at this location is goto __reset. This code is added by the
linker to make the program branch to the start of the code in the Tut6014.s file.
The code uses the __reset label at the start of the executable code and
declares the label as global to have visibility outside the source file (see
Example 2-1).
The linker also provides values for the __SP_init and __SPLIM_init
constants to initialize the stack pointer (W15), since the linker determines what
RAM is available for the stack.
