Instances in the MCU domain:
- MCU_RTI0 is dedicated to the MCU cluster (MCU_R5FSS0) in lockstep and when unlocked serves as a Windowed Watchdog for the first R5F CPU core in the MCU domain (MCU_R5FSS0_CORE0).
- MCU_RTI1 is dedicated to the second R5F CPU core of the MCU cluster (MCU_R5FSS0_CORE1) when unlocked.
Instances in the MAIN domain: They are intended to function as a Digital Windowed Watchdog for the CPU core that they are associated with, that is:
- RTI0 is dedicated to the first A72 CPU core in the A72 cluster (A72SS0_CORE0)
- RTI1 is dedicated to the second A72 CPU core in the A72 cluster (A72SS0_CORE1)
- RTI15 is dedicated to the GPU
- RTI16 is dedicated to the C7x DSP
- RTI24 is dedicated to the first C66x DSP core (C66SS0_CORE0)
- RTI25 is dedicated to the second C66x DSP core (C66SS1_CORE0)
- RTI28 is dedicated to the first R5F CPU core in the Main domain (R5FSS0_CORE0)
- RTI29 is dedicated to the second R5F CPU core in the Main domain (R5FSS0_CORE1)
- RTI30 is dedicated to the third R5F CPU core in the Main domain (R5FSS1_CORE0)
- RTI31 is dedicated to the fourth R5F CPU core in the Main domain (R5FSS1_CORE1)
It is not intended to use an RTI that is provisioned for a particular CPU core with a different CPU core.
