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_ICSSG has a separate mapping to device input signals - PRGn_PRU0_GPI[19:0] for the PRU0 core and PRGn_PRU1_GPI[19:0] for the PRU1 core. There are 80 general purpose inputs in total. For more details, refer also to the PRU_ICSSG Environment. See the device's system reference guide or datasheet for device specific pin mapping.
