Overview
|
|
========
|
|
The EWM Example project is to demonstrate usage of the KSDK EWM driver.
|
|
In the example, EWM counter is continuously refreshed until button is pressed.
|
|
Once the button is pressed, EWM counter will expire and interrupt will be generated.
|
|
After the first pressing, another interrupt can be triggered by pressing button again.
|
|
|
|
Note: In flash boot mode, if you want to use the IDE reset program, please use systemReset.
