To run the Quick Start example project, follow the instructions below:
1. On power up or RESET, the user LED (LED1) starts blinking red at 1 Hz.
2. Press the user button (S1, PUSH BTN) on the EK-RA4M1 board to change the blinking frequency of
LED1. With every button press, the frequency will switch from 1 Hz to 5 Hz to 10 Hz and cycle back.
