Detailed Description

SDHostCC3200 Hardware attributes.

The SDHostCC3200 configuration structure is passed to the SDHostCC3200 driver implementation with hardware specifics regarding GPIO Pins and Ports to be used.

The SDHostCC3200 driver uses this information to:

• Configure and reconfigure specific ports/pins to initialize the SD Card for SD mode
• Identify which GPIO port and pin is used for the SDHost clock, data and command lines

These fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For CC32xxWare these definitions are found in:

• inc/hw_memmap.h
• inc/hw_ints.h
• driverlib/gpio.h
• driverlib/pin.h
• driverlib/prcm.h
• driverlib/sdhost.h

An example configuration structure could look as the following:

const SDHostCC3200_HWAttrs sdhostCC3200HWattrs[] = {
    {
        .clkRate = 8000000,
        .intPriority = ~0,
        .baseAddr = SDHOST_BASE,
        .dataPin = PIN_06,
        .dataPinMode = PIN_MODE_8,
        .cmdPin = PIN_08,
        .cmdPinMode = PIN_MODE_8,
        .clkPin = PIN_07,
        .clkPinMode = PIN_MODE_8,
    }
};
