I2C pins

Other Parts Discussed in Thread: TMS570LS3137

Hi

I have the following question:

Is possible to use at the same time the I2C function  and the MIBSPI3 SPI function on a TMS570LS3137 ??.

On MIBSPI3 I use only the CS0 pin to enable the external device. CS2 and CS3 pin are not used by MIBSPI but I want use them as SDA and SCL for I2C function.

Thank.

    Hi Livio,

    Yes, you can control the functionality per pin.
    MIBSPI3NCS[2]/I2C_SDA/N2HET1[27] and MIBSPI3NCS[3]/I2C_SCL/N2HET1[29] can be assigned to I2C functionality while using other pins for MibSPI.
    You may refer to the TRM section 4.6 for pin mux configuration.
