AWR1642: The pinmux pull config about the R4、P4 in HW trigger mode

Hi all

       There is a  question about the  pinmux pull config about the R4、P4 in HW trigger mode.

       We used the HW trigger into SYNC_IN to trigger the frame start..Due to circuit design issues, we neeed to disable the pull down about  PINMUX. Burt after config the HW trigger，No matter how the pins are configured， Pin level is pulled low.So the Pinmux couldn't be triggered.

   There are some configs after config the HW trigger mode

     Pinmux_Set_OverriideCtrl(SOC_XWR16XX_PINP4_PADBB,PINMUX_OUTPUT_DIS,PINMUX_INPUT_EN);

    Pinmux_Set_FuncSell(SOC_XWR16XX_PINP4_PADBB,SOC_XWR16XX_PINP4_PADBB_SYNC_IN);

    Pinmux_Set_Pull(SOC_XWR16XX_PINP4_PADBB,PINMUX_DISABLE_PULLS);

    Pinmux_Set_OverriideCtrl(SOC_XWR16XX_PINR4_PADBF,PINMUX_OUTPUT_DIS,PINMUX_INPUT_EN);

     Pinmux_Set_FuncSell(SOC_XWR16XX_PINR4_PADBF,SOC_XWR16XX_PINR4_PADBF_GPIO_31);

      Pinmux_Set_Pull(SOC_XWR16XX_PINR4_PADBF,PINMUX_DISABLE_PULLS);
