Enumeration Type Documentation

◆ nxp_pint_trigger

Driver for Pin interrupt and pattern match engine in NXP MCUs.

The Pin interrupt and pattern match engine (PINT) supports sourcing inputs from any pins on GPIO ports 0 and 1 of NXP MCUs featuring the module, and generating interrupts based on these inputs. Pin inputs can generate separate interrupts to the NVIC, or be combined using the PINT's boolean logic based pattern match engine. This driver currently only supports the pin interrupt feature of the PINT.
