INSERT DESCRIPTION OF THE ACTUAL RESULT
twi.c failed to compile with MSP430G2553 because it does not have EUSCI_B0.

List the steps to reproduce the problem.

INSERT STEPS TO REPRODUCE THE PROBLEM
MSP430G2553 has an USCI_B0 but does not have EUSCI_BO. twi_disable cannot handle cases such as MSP430_HAS_USCI
MSP430_HAS_USCI_B0 or MSP430_HAS_USCI_B1.
The solution is:
twi.c should be change from

void twi_disable(void)
{
#if defined(__MSP430_HAS_USI__)
    /* Disable USI */
    USICTL0 |= USISWRST;
#else
     /* Disable USCI */
    UCBzCTLW0 |= (UCSWRST);
#endif
}

to

void twi_disable(void)
{
#if defined(__MSP430_HAS_USI__)
    /* Disable USI */
    USICTL0 |= USISWRST;
#elif defined(__MSP430_HAS_USCI__) \
 || defined(__MSP430_HAS_USCI_B0__) || defined(__MSP430_HAS_USCI_B1__)
    UCB0CTL1 |= UCSWRST;
#else
     /* Disable USCI */
    UCBzCTLW0 |= (UCSWRST);
#endif
}

Thank you.
