If the PRE bit is set, the RTI will continue to run in pseudo-stop mode.

9.4.7.1
The CRGV4 block behaves as described within this specification in all normal modes.
9.4.7.2
The VCO has a minimum operating frequency, f
to a failure or due to long crystal start-up time, the bus clock and the core clock are derived from the VCO
running at minimum operating frequency; this mode of operation is called self-clock mode. This requires
CME = 1 and SCME = 1. If the MCU was clocked by the PLL clock prior to entering self-clock mode, the
PLLSEL bit will be cleared. If the external clock signal has stabilized again, the CRG will automatically
select OSCCLK to be the system clock and return to normal mode. See
Checker” for more information on entering and leaving self-clock mode.
