CCS/MSP432P4111: I2C_START_INTERRUPT

Part Number: MSP432P4111

Tool/software: Code Composer Studio

What are the probabilities of occurring  I2C start interrupt (EUSCI_B_I2C_START_INTERRUPT) in the MSP432P4111 device?

Does I2C start interrupt (EUSCI_B_I2C_START_INTERRUPT) in MSP432P4111 work with EUSCI_B_I2C in Master transmitter configuration?

    Hello,

    This flag is set when the I2C module detects a START condition together with its own address. 

    No the start condition interrupt flag is used in slave mode only. 

    For more information on this, please refer to section 26.3.10 eUSCI_B Interrupts in I2C Mode in the Technical Reference Manual 

    Thanks,

    Alexis

    Thanks a lot, Alexis.  I got the point.

    1.) Why this I2C start interrupts for "I2c master transmitter" Not implemented to detect completion of a start signal sent by this  I2C master to slave.

    2.)Now when the "I2c master transmitter" sent a start signal to the slave, "I2c master transmitter" needs to wait in a while loop to poll the UCTXSTT Bit to get the status. 

     Thank you.
