30.5.4 Events
The NVMCTRL can take the following actions on an input event:
- Write zeroes in one Data FLASH row: Refer to 30.6.7 Tamper Erase for details.
- Write a page in the FLASH or in the Data FLASH: Refer to 30.6.6 Event Automatic Write for details.
The NVMCTRL uses only asynchronous events, so the asynchronous Event System channel path must be configured. By default, the NVMCTRL will detect a rising edge on the incoming event. If the NVMCTRL action must be performed on the falling edge of the incoming event, the event line must be inverted first. This is done by setting the corresponding Event Invert Enable bit in Event Control register (NVMCTRL.AUTOWINV=1).
