Interrupts on the i.MX RT1062: GPIO vs ADC vs FlexPWM, and Auditing Your NVIC Table
GPIO, ADC and FlexPWM interrupts follow one NVIC pattern but differ in where the trigger lives and how the flag clears. Plus the audit that matters with FreeRTOS: which ISRs sit above the syscall barrier, and therefore must never touch a FreeRTOS API.
