I have a question about the PEX_x_CLKREQ_N pin type as described in the AGX Orin Design Guide.
When Jetson is RC, Table 7-16 shows it as input/output (I/O), but Table 7-18 shows it as input (I).
When Jetson is acting as an RC, I think this pin type is input, not bidirectional, is this correct?
Yes, this pin is input as Root Port. But the pin type itself is I/O as it can be ouput as End Point. We’ll consider if need to change to Input in Table 7-16, thanks.
