GPIO interrupts

Question: 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.
