8. Choose Run > Halt to stop execution after a few seconds.
The Template component is a view linked to a specific memory location in TargetObject.
In the source code of the test program, you can find a variable associated with it:
#define PORT_DATA (*((volatile unsigned char *)0x0210))/* Value
with range 0..255 */
The Template component polls this value and displays it in a speedometer-like outlook.
The procedure IO_Show in io_demo.c, shown in Listing 28.6 , increments or
decrements this value, depending on the raise direction. The raise direction depends on a
global variable dir that is turned back when the top or bottom value is reached.
