Hi,
I am developing a board using 66AK2G12 SoC and I'd like to have a confirm about the unused pins.
I read the datasheet where the "Connections for Unused Pins" is described. This chapter defines explicity the connection for several pins and recommends to tie-off unconnected pads because their internal pull up/down could be weak but the external pull up/down is not mandatory for the signal balls without Pad Configuration Register. For example we don't use ECC for DDR therefore, according to explanation above, can I leave DDR3_CB0X unconnected since these pads are not defined with a pad configuration register?
Thanks for the collaboration.
