Real-Time Interrupt Enable — This read-write bit enables real-time interrupts.
0 Real-time interrupts disabled.
1 Real-time interrupts enabled.
Real-Time Interrupt Delay Selects — These read/write bits select the period for the RTI. See
To power down the internal 1-kHz oscillator completely in MCU STOP
mode, RTIS bits must be selected to %000 and RTICLKS bit must be set
to 1.
