6.Reviewing the Tutorial Program
This section will look at each section of the tutorial code and basic debugging functionality in Cu.
6.1 Program Initialisation
Before the main program can run, the microcontroller must be configured. Due to the debugger configuration
used for the Tutorial project and the rest of the sample projects, the user will not be able to step through the
hardware initialisation code. Please refer to Section 3.3 to change the entry point after programming the
microcontroller. Specify ‘_R_Systeminit’ as the function name if viewing of hardware initialisation is desired.
The initialisation code is executed every time the device is reset via the reset switch or from a power reboot.
The user is advised not to use the ‘step’ feature of the debugger to exit the R_Systeminit function.
Ensuring the Tutorial program has been downloaded onto the RX111; press the ‘CPU Reset’ button
on the Debug Toolbar.
