DS90UH948-Q1: For unused ports as below picture, How to deal-with?

Part Number: DS90UH948-Q1

Checked the 948-Q1 spec, it suggest to use pull-down resistor for those unused GPIO ports.

Q: Considering the initialization of chip, if we ignore the it during initialization, let them floating. Then after that, configure the ininternal register, make them as "Pull-Down". Is that OK?

  • Hello ,

          There are "a weak internal pulldown (3 μA)" in listed pins, please check "Table 5-1. Pin Functions" for detailed information. 

          if you do not external pulldown, it is ok that  pulled down by register  with more power consumer maybe.
