unsigned int	intNum
unsigned int	intPriority

Detailed Description

I2CCC3200 Hardware attributes.

The baseAddr and intNum fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For CC3200Ware these definitions are found in:

• inc/hw_memmap.h
• inc/hw_ints.h

intPriority is the I2C peripheral's interrupt priority, as defined by the underlying OS. It is passed unmodified to the underlying OS's interrupt handler creation code, so you need to refer to the OS documentation for usage. For example, for SYS/BIOS applications, refer to the ti.sysbios.family.arm.m3.Hwi documentation for SYS/BIOS usage of interrupt priorities. If the driver uses the ti.drivers.ports interface instead of making OS calls directly, then the HwiP port handles the interrupt priority in an OS specific way. In the case of the SYS/BIOS port, intPriority is passed unmodified to Hwi_create().

A sample structure is shown below:

const I2CCC3200_HWAttrs i2cCC3200HWAttrs[] = {
    {
        .baseAddr = I2CA0_BASE,
        .intNum = INT_I2CA0,
        .intPriority = (~0)
    }
};
