The PRU-ICSS supports a scratch pad with up to four independent banks accessible by the PRU cores. The PRU cores interact with the scratch pad through broadside load/store PRU interface and XFR instructions. The scratch pad can be used as a temporary place holder for the register contents of the PRU.
