//  MSP430F552x Demo - USCI_B0 I2C Master TX single bytes to MSP430 Slave
//
//  Description: This demo connects two MSP430's via the I2C bus. The master
//  transmits to the slave. This is the master code. It continuously
//  transmits 00h, 01h, ..., 0ffh and demonstrates how to implement an I2C
//  master transmitter sending a single byte using the USCI_B0 TX interrupt.
//  ACLK = n/a, MCLK = SMCLK = BRCLK = default DCO = ~1.045MHz
//
// ***to be used with "MSP430F55xx_uscib0_i2c_07.c" ***
