4.14 Interrupt

The SK EVM supports the following timer and interrupt options.

Three interrupts are available to provide reset for MCU_PORz and MCU_RESETz and RESET_REQz. One push button switch is available for GPIO interrupt which is connected to both main domain and MCU domain GPIO pin.

Warm reset can also be applied through the test automation header.
