Each PRU (PRU0 and PRU1) has a dedicated 12KB of Instruction Memory which needs to be initialized by an external to PRU-ICSS Host processor before a PRU core executes any instructions.
The PRU-ICSS PRU0/1_IRAM regions are ONLY accessible from controllers, external to the PRU-ICSS (like Arm) when the PRU0/PRU1 is NOT running. The access is via PRU-ICSStarget port on the device CBASS0 interconnect.
