Hi,
In mmwave hardware design review tool, I found below statement.
"Any unused digital I/O pins can be left NC. Otherwise, follow pullup/pulldown requirement for unused signals."
I didn't find any unused pin requirement in AWR6843AOP datasheet. Does it mean that all unused digital I/O can be left NC? For example, if SPI is not used, customer can let all SPI related pins, such as CS/CLK/data, float.
Would you pls help to confirm?
Thanks,
Chris
