1. Project Overview:
    This example project showcases a typical use case of the Multi-Function Timer Unit 3 (MTU3) on the RZ/N2L microcontroller, 
    demonstrating how to generate and dynamically adjust PWM signals. The MTU3 module is initialized to produce PWM outputs 
    with a duty cycle that transitions continuously through the following sequence: 25% → 50% → 75% → back to 25%. 
    Each transition occurs at a fixed interval of 2 seconds, allowing for clear observation of the waveform changes.
    Any API/event failure message is also displayed.

2. Software Requirements:
    Renesas Flexible Software Package (FSP): Version 4.1.0
    e2 studio: Version 2026-04.1
    GCC ARM Embedded Toolchain: Version 13.3.1.arm-13-24
    SEGGER J-Link RTT Viewer: Version 8.60

3. Hardware Requirements:
    RZ supported boards: RZ/N2L-RSK.
    1 x RZ board.
    1 x USB Type-C cable.
    1 x USB Type-A to micro USB cable.

4. Hardware Configurations:
    (1) Boot Mode:
        16-bit bus boot mode (NOR flash).
    (2) Set for DIP switches and jumpers as follow:
    Hardware Connection:
    
        1. *External flash memory must be blank to start this sample program (RAM execution).
        NOR flash memory on this board is blank, so set the operating mode switch for 16-bit bus boot mode (NOR flash).
        SW4.1 : ON
        SW4.2 : OFF
        SW4.3 : ON
        SW4.4 : ON

        2. *This sample program runs on TCM and CPU frequency is set to 800MHz in the start up process.
        Therefore, the following settings (MDW = 1) are required.
        SW4.5  : OFF

        3. * Use MTIOC1A(P01_6) ... RSK board CN1.1
        SW4.7 : ON

        4. PWM Output

        |       CN1          |     PWM Output     |
        |--------------------|--------------------|
        |      CN1.1    <----|---->  MTIOC1A      |
        |--------------------|--------------------|

Note:
1. Segger RTT block address may be needed to download and observe EP operation using a hex file with RTT-Viewer.
   RTT Block address for hex file committed in repository are as follows:
   a. e2studio: 0x30100000

2. If an EP is modified, compiled, and downloaded please find the block address (for the variable in RAM called _SEGGER_RTT) 
   in .map file generated in the build configuration folder (Debug/Release).
