/**
* 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
