GPIO interrupts

Last Updated: September 20, 2011

Occasionally when constant GPIO interrupts occur, the CY3654 will halt. This has been found to happen most often at an 800Hz interrupt rate. The halt can happen anywhere from a couple of seconds to 10 minutes after the first GPIO interrupt.


This is a known problem with the CY3654. We're still investigating the cause. Please refer to the CY3654-P05 errata for a list of known issues. Open a support case for this document.
