7.5 Steps to Run the Application
The following table shows the steps to run the Clock Changing and LPM Transition application. On power up,
when the board is connected to RTT, it will display the welcome message. To change the clock/LPM and run
through the different use cases in this application, use the following tables as reference. These tables have
the list of events, current mode, the new transition states and the expected outcome.
7.5.1 Clock Changing:
The user button has two functions, based on how long you press and hold it. In the clock changing mode, the
user button pressed and held for 3-6 seconds selects the different system clocks for the MCU. Whereas the
user button pressed and held for 1-2 seconds exits the clock changing mode and enters into LPM for the
configured clock. The details are as shown in Table 8.

Events
System Clock
User Button – Long Press
User Button – Short Press
MOSC
(Main Oscillator)
Changes the System Clock to HOCO
Exits the Clock State Machine and enters
the LPM State Machine for the configured
clock MOSC.
HOCO
(High speed on-
chip oscillator)
Changes the System Clock to MOCO
Exits the Clock State Machine and enters
the LPM State Machine for the configured
clock HOCO.
MOCO
(Medium speed on-
chip oscillator)
Changes the System Clock to LOCO
Exits the Clock State Machine and enters
the LPM State Machine for the configured
clock MOCO.
LOCO
(Low speed on-chip
oscillator)
Changes the System Clock to SOSC
Exits the Clock State Machine and enters
the LPM State Machine for the configured
clock LOCO.
SOSC
(Sub Oscillator)
Changes the System Clock to MOSC
Exits the Clock State Machine and enters
the LPM State Machine for the configured
clock SOSC.
Note: MOSC and SOSC are not supported on FPB-RA6E1 and FPB-RA4E1 by default.
