Detailed Description

I2CMSP432 Hardware attributes These fields, with the exception of intPriority, are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For MSP430Ware these definitions are found in:

• i2c.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 I2CMSP432_HWAttrs i2cMSP432HWAttrs[] = {
    {
        .baseAddr = EUSCI_B0_BASE,
        .intNum = INT_EUSCIB0,
        .intPriority = (~0),
        .clockSource = EUSCI_B_I2C_CLOCKSOURCE_SMCLK
    }
};
