Part Number: IWR1642

Hi,

How to configure GPIO48 in IWR1642? The customer could control any other gpio except for gpio48. Is there anything that needs special attention?

    Nancy Wang, 

    By default power up this pin is reserved, However it could be pin muxed as DMM_SYNC pin or debug TRACE control pin, For more details please refer to the IWR1642 datasheet GPIO functionality is not available on this pin.On the EVM N14 symbol ball location is called GPIO but it's mapped to DMM_SYNC functionality. 

    Thanks and regards,
