For many of the pins the datasheet states to tie to ground through a resistor, for example GPIO_3P3_0 states to tie to ground through a resistor to safeguard against misconfiguration, I am wondering if this should be a 0 ohm jumper to ground or if there is a preferred pull-down value i.e 10K?
It is preferred to ground through 10 K resistor to avoid misconfiguration.
I have a follow up question, for pin P1 (AUX_SYNTH_VTUNE) there is no indication for what to do with this pin if unused. As a secondary question I cannot find any documentation in the datasheet or hardware reference manual for what AUX_SYNTH_VTUNE and AUX_SYNTH_OUT do so I am planning leave them as unused in my design.
P1 (AUX_SYNTH_VTUNE) when unused do not connect (Leave floating)
Aux PLL generates the clock sources required for internal calibrations.
