|
* @brief Flash demo example
|
|
*
|
|
* The LED1 (P1.1) of the RelaxKit is switched on.
|
|
* The flash example erases the logical sector 11.
|
|
* Then programs a page in the mentioned logical sector with a given data pattern.
|
|
* Finally the demo code checks the whether the data is programmed correctly.
|
|
* If data is not programmed correctly LED1 of the RelaxKit will blink,
|
|
* otherwise the LED1 will switch off.
