One R5F cluster (MCU_R5FSS0) is present within the MCU domain (MCU_R5FSS0), and the remaining three clusters are present in the MAIN domain (MAIN_R5FSS0, MAIN_R5FSS1 & MAIN_R5FSS2). The functionality of the R5FSS is same as the R5FSS functionality on earlier K3 platform devices J721S2. Each of the R5FSS can be configured at boot time to be either run in a LockStep mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode.
