TDA4VM: TDA4 OSPI FLASH Device DQS pull down resistance

TDA4VM: TDA4 OSPI DQS pull down resistance recommend

Hi,

  I understand a pulldown resistor is recommended at DQS according to this stream. But what value should it be? The EVM schematic uses 1K but the Jacinto7 AM6x/DRA8x/TDA4x Schematic Checklist (link) says it is recommended to add a weak (100k-ohm) pull-down resistor on DQS.
