1. Project Overview:
    The example project demonstrates the typical use of the INTC NMI module APIs.
    The project initializes the IRQ interrupt in Interrupt Controller 
    User is requested to press the SLEEP push button on Carrier Board to trigger the external irq and this then will start toggling of user LED.

2. Hardware and Software Requirements:
    External Hardware : Pmod LED
    Software          : JLink RTT Viewer v7.96j

3. Hardware settings:
    Boot Mode:
    Boot mode 3 (SCIF Downloading) with CA55 cold boot

    Board:
    RZ/G3E  Evaluation Kit (SMARC)

    Hardware Connection:

    (1) Set for DIP switches and jumpers as follow.

        |               | SW_MODE-4    : ON                  |
        |               | PMOD_PWR_SEL : Jumper connects 2-4 |
        +---------------+------------------------------------+

    (2) Connect the J-Link Base and the connector on the SMARC Module Board with JTAG cable.
        When connecting the conversion adapter "J-Link 9-pin Cortex-M Adapter" made by SEGGER will be required.

    (3) Connect PMOD1_6A PIN9 on SMARC Carrier Board and Pmod LED.

Note:
1. Segger RTT block address is required to connect J-Link RTTViewer. 
   The RTT block address can be confirmed by searching "_SEGGER_RTT" in .map file 
   which is located in Debug folder and generated when building.
