|
* at32_waste() is the logic that will be executed when portions of kernel
|
|
* or user-app is polling some register or similar, waiting for desired
|
|
* status. This time is wasted away. This function offers a measure of
|
|
* badly written piece of software or some undesired behavior.
|
|
*
|
|
* At the same time this function adds to some IDLE time which portion
|
|
* cannot be used for other purposes (yet).
