How to clear a GPIOTE port event register?

[jklai05]

I am confused from reading the nRF52832 Product Specification on how to clear the GPIOTE port event (EVENTS_PORT) register?

On Section 21.2 (Port event) on page 158, it states "clear any potential event that could have occurred during configuration (write '1' to EVENTS_PORT), and finally enable interrupts".

On Section 15.6 (Events) which describes events in general, it states an "event register is only cleared when firmware writes a '0' to it.

Is there a typo in the documentation, or is the GPIOTE event register different than the rest?

Thanks,

John

Hi John,

 

On Section 21.2 (Port event) on page 158, it states "clear any potential event that could have occurred during configuration (write '1' to EVENTS_PORT), and finally enable interrupts".

It seems you've found a typo in our docs. This should of course be "write '0' to EVENTS_PORT". I will report this internally to our technical writers. Thanks for letting us know!

Best regards,

Håkon
