I2CMSP432E4 Hardware attributes.
The baseAddr and intNum fields are used by driverlib APIs and therefore must be populated by driverlib macro definitions. For MSP432E4 driverlib these definitions are found in:
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.dpl 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:
uint32_t I2CMSP432E4_HWAttrs::baseAddr |
I2C Peripheral's base address
uint32_t I2CMSP432E4_HWAttrs::intNum |
I2C Peripheral's interrupt vector
uint32_t I2CMSP432E4_HWAttrs::intPriority |
I2C Peripheral's interrupt priority
uint32_t I2CMSP432E4_HWAttrs::sclPin |
I2C Serial Clock Line pin configuration
uint32_t I2CMSP432E4_HWAttrs::sdaPin |
I2C Serial Data Line pin configuration
uint8_t I2CMSP432E4_HWAttrs::masterCode |
I2C Master Code. The master code can be between 08h to 0Fh. Each master on a shared bus should use a unique master code. The master code is only used when operating at a bit rate of I2C_3330kHz. Therefore, this parameter is ignored when operating at other bit rates.
