Hi team,
We are developing on the PRU core and are in the need of bidirectional open drain signals. As in section 7.2 of the training video here, we plan to use one of the PRU IEP Digital I/O for the open drain output and one of the PRU GPIO for the input.
We do not have anymore GPI on PRU-ICSS1 available due to pinmuxing. Even though the IEP DIO (Table 4-50 of the datasheet) are in the PRU-ICSS1, we can still use them with GPI from PRU-ICSS0-PRU0, correct? For example, can we tie pr1_edio_data_out0 to pr0_pru0_gpi0 to create our bidirectional open drain pin? In this case, our application will then have to run on PRU-ICSS0-PRU0?
Regards,
Akash
