S12 Clock, Reset and Power Management Unit (S12CPMU)
7.3.2.8
This register selects the time-out period for the Real Time Interrupt.
The clock source for the RTI is either IRCCLK or OSCCLK depending on the setting of the RTIOSCSEL
bit. In Stop Mode with PSTP=1 (Pseudo Stop Mode) and RTIOSCSEL=1 the RTI continues to run, else
the RTI counter halts in Stop Mode.

7
A write to this register starts the RTI time-out period. A change of the
RTIOSCSEL bit (writing a different value or loosing UPOSC status)
re-starts the RTI time-out period.
