The pru<n>_r31_status[0:19] bits of the internal PRU register file are mapped to device-level, general purpose input pins (PRU0_GPI[0:19]). In GPI Direct Input mode, PRU0_GPI[0:19] feeds directly to pru<n>_r31_status[0:19].
Each PRU of the PRU-ICSS has a separate mapping to device input signals - PRn_PRU0_GPI[19:0] for the PRU0 core and PRn_PRU1_GPI[19:0] for the PRU1 core. There are 40general purpose inputs in total. For more details, refer to the PRU-ICSS Environment. See the device's system reference guide or datasheet for device specific pin mapping.
