S12 Clock, Reset and Power Management Unit (S12CPMU)
10.3.2.8
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.

Decimal or Binary Divider Select Bit — RTDEC selects decimal or binary based prescaler values.
0 Binary based divider value. See
1 Decimal based divider value. See
Real Time Interrupt Prescale Rate Select Bits — These bits select the prescale rate for the RTI. See
Table 10-10
Real Time Interrupt Modulus Counter Select Bits — These bits select the modulus counter target value to
provide additional

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.
