EP interrupt handler: Increments the overflow member of the counter structure, for each counter that is in use and has an overflow.
This handler is not configured or used automatically. You must configure the interrupt handler for the EP, using Cy_SysInt_Init(). Typically you configure the system to use Cy_Profile_ISR() as the overflow interrupt handler. You can provide a custom interrupt handler to perform additional operations if required. Your handler can call Cy_Profile_ISR() to handle counter overflow.
