The PRU Real Time Status Interface directly feeds information into register 31 (R31) of the PRU’s internal register file. The firmware on the PRU uses the status information to make decisions during execution. The status interface is comprised of signals from different modules inside of the PRU-ICSS which require some level of interaction with the PRU. More details on the Host interrupts imported into bit 30 and 31 of register R31 of both the PRUs is provided in the , PRU-ICSS Local Interrupt Controller.
