LMK04616: LMK04616

Part Number: LMK04616
Other Parts Discussed in Thread: USB2ANY

Hello,

I am not able to configure the LMK04616 SPI interface  in 3-wire mode. Could you give the access sequence to enable it.

NB. The device works OK if I use the 4-wire interface

    Hello Joel,

    Please refer to page 98 of datasheet.  To use 3-wire mode, you must program...

    • SPI_EN_THREE_WIRE_IF in 0x8d[7] = 1.
    • SPI_SDIO_OUTPUT_MUTE in 0x8d[4] = 0.
    • SPI_SDIO_OUTPUT_INV in 0x8d[3] = 0 (unless there is some inverting hardware you need to compensate for)

    Please note the USB2ANY does not support 3-wire mode.
