* @brief CCU4 concatenation demo example
|
||
|
|
*
|
||
|
|
* The example show how to concatenate to CCU4x slice timers.
|
||
|
|
* The example provides an API (see timer.h) to treat both slices as a 32bit timer.
|
||
|
|
* The timer has a resolution of 1/fCPU
|
||
|
|
*
|
||
|
|
* In the example LED1 toggles at a frequency of 1Hz (polling the timer) and LED2 toogles at a frequency of 2Hz (using the user callback)
