TMS320F280049: Risks of insufficient pull up resistor on XRSn pin

Sheldon He

Hi experts,

Our datasheet recommended 2.2k to 10k pull up resistor to VDDIO on XRSn pin of F280049, what will be this possible risk if pull up resistor is 50k?

Thanks

Hi Sheldon,

With 50K pull-up register risk will be resetting the device with small noise which will be specific to customer board and application.
