-/**
- * This is a simple LED toggle test for the V850ES/Fx3.
- *
- * Creates two task that control one LED each.
- *
- * The first task toggles a LED with a frequency of 1Hz by using the vTaskDelay
- * function. So the task is yielded for 1 seconed after each LED switch.
- *
- * The second LED also starts with a toggling frequency of 1Hz but this frequency
- * can be increased by pushing the switch button conected to pin INTP0.
- * When the switch is pushed it is detected by an interrupt. When the interrupt
- * occurs a flag is set in the ISR and sent to the third task by using a queue.
- * Therefore the xQueueSendFromISR() function is called from within the ISR to
- * write the flag value to the queue. The task uses the xQueueReceive() function
- * to read the flag value from the queue.
- * If the flag value changed from the last task activation the yield time for the
- * second LED is incremented by 100ms. If the yield time reaches a time greater
- * then 3 seconds it is set back to 1 second within task 3.
- *
- * Also a check function is implemented to check if the task still run properly
