i2c_master_rx_multi_int

This example shows how to configure the I2C module as a master for multi-byte reception with teh help of interrupts. The address of the slave module that the master communicating with also set in this example. This example uses the interrupt driven mode to receive data.

This example uses the following peripherals and I/O signals. You must review these and change as needed for your own board:

• I2C peripheral
• GPIO Port peripheral (for I2C pins)
• SCL2
• SDA

This example uses the following interrupt handlers. To use this example in your own application you must add these interrupt handlers to your vector table.

• USCI_B0_VECTOR
