TMS570LS1115 MibSPI Pin config

唐旗
Prodigy 120 points

Hi,I am using 570 mibspi ,In hardware I use MibSpi1SIMO[1],MibSpi1SOMI[1],MibSpi1CLK and MibSpi1CS[1] connect with other chip.

I config the pin function as below,and use mibspi1 as normal spi,without multi-buff.

    mibspiREG1->PC0 = (uint32)((uint32)0U << 0U)  /* SCS[0] */
                    | (uint32)((uint32)1U << 1U)  /* SCS[1] */
                    | (uint32)((uint32)0U << 2U)  /* SCS[2] */
                    | (uint32)((uint32)0U << 3U)  /* SCS[3] */
                    | (uint32)((uint32)0U << 4U)  /* SCS[4] */
                    | (uint32)((uint32)0U << 5U)  /* SCS[5] */
                    | (uint32)((uint32)1U << 8U)  /* ENA */
                    | (uint32)((uint32)1U << 9U)  /* CLK */
                    | (uint32)((uint32)0U << 10U)  /* SIMO[0] */
                    | (uint32)((uint32)0U << 11U)  /* SOMI[0] */
                    | (uint32)((uint32)1U << 17U)  /* SIMO[1] */
                    | (uint32)((uint32)1U << 25U); /* SOMI[1] */

I can not send data out,I watch the pin wave by the Osc,but there is no change when I send data.

So can you guys help me? thank you!
