Can you explain what the modes in the pin mux utility refer to?

I want to use a SPI, the GPMC and DDR interface for my configuration, any conflicts doing that?

    Hi Paul,

    Can you elaborate on what information you required?

    You can take the pinmux utility from

    http://software-dl.ti.com/dsps/dsps_public_sw/am_bu/ampinmux/latest/index_FDS.html

    In the tool we can see all the modes (0-7). We can select the module on "left-top corner" so that the tool will show those module specific pins in current view.

    Regards

    Hi Paul,

    We can configure the same pin for 8 different functionalities if applicable, depending on the usecase.

    If you want to configure GPMC_A0_MUX0 as pin functionality, you have to write the coresponding value to "Pad Control Register" based on mode, type of signal.

    GPMC_A0_MUX0 GMII2_TXEN RGMII2_TCTL RMII2_TXEN GPMC_A16_MUX0 PR1_MII_MT1_CLK EHRPWM1_TRIPZONE_INPUT_MUX1
    GPIO1[16]

    You can go through TRM, section "9.2.2 Pad Control Registers" for more details

    Regards
