5.2.2 TBM Reference Clock Selection
The timebase module reference clock (OSCCLK) is selected by configuring two bits in the CONFIG2
register, at $001D. See

Address:
The internal oscillator is a free running oscillator and is available after each
POR or reset. It is turned-off in stop mode by setting the STOP_ICLKDIS
bit in CONFIG2.
The RCCLK or XCLK is only available if that clock is selected as the CGM
reference clock, whereas the ICLK is always available.
