•
Right click the ‘Flash_LED()’
function call and select ‘Go to
Here’ to execute the program up to
this line. The ‘Display_LCD()’
function is used to write “Renesas”
onto the top line and “RX111” onto
the bottom line.
•
Set a software breakpoint on the
‘timer_adc()’ function call by
clicking on the On-Chip Breakpoint
column to the left of the number

•
The Flash_LED function toggles
the LEDs, through the
Toggle_LED function at regular
intervals.
•
The ‘while’ statement checks the
g_switch_flag variable for switch
press detections and the value of
the flash_count variable, which
counts down with every LED flash.
Once a switch has been pressed
or the count variable reaches zero,
the function exits the ‘while’ loop.
•
Press the button to resume
program execution.
