Hello Whong,

rtiREG1->SETINTENA=0x00000002 is to enable the notification of RTI compare 1.

Writing 1 to bit 0 of RTIGCTL register is to enable the counter 0.

Since the interrupt is enabled, you can check the flag which is set in the RTI notification. If the flag is set, the RTI is running.

Another way, you can check the FRC register. If the value in FRC register is changing, the RTI counter is running.
