  2. Connect to the PKOB4 Virtual COM port and configure the serial settings as follows:
    • Baud : 115200
    • Data : 8 Bits
    • Parity : None
    • Stop : 1 Bit
    • Flow Control : None
  3. Build and Program the application project using its IDE.
  4. System time is displayed in terminal session as RTC is configured in calendar mode.
  5. To generate a tamper event, press switch.
  6. Upon detection of the tamper event, LED will be toggled and the console output will be updated as follows:
