MSP430F5659: UCB1 I2C not working

I have working I2c code that was running on a previous design using a MSP430F5438A micro on UCB0. We switched to the MSP430F5659 and I needed to move to the UCB1 module on port 8 pins 5 and 6. I am running as the master and I get nothing on those port pins. There are external pull-ups on the board and both lines are always high. the I2C routines are polling, so no interrupts used.

I tried switching to the UCB0 module with the same code and it works fine...went back to UCB1 and still nothing. Any ideas as to why it wouldn't be working? Am i missing something odd about port 8?

Below are my I2C routines...

void InitializeI2C(void)
{
P8SEL |= BIT6; // enable SCL pin
P8SEL |= BIT5; // enable SDA pin

UCB1CTL1 |= UCSWRST; // hold serial controller in reset

UCB1CTL0 &= ~UCSLA10; // 7 bit slave address
UCB1CTL0 &= ~UCMM; // single master environment
UCB1CTL0 |= UCMST; // master mode
UCB1CTL0 |= UCMODE_3; // I2C mode
UCB1CTL0 |= UCSYNC; // synchronous mode

UCB1CTL1 |= UCSSEL_1; // select ACLK for clock source

UCB1BR0 = (I2C_CLOCK_PRESCALER & 0xFF); // LSB of clock prescaler
UCB1BR1 = (I2C_CLOCK_PRESCALER >> 8); // MSB of clock prescaler

UCB1CTL1 &= ~UCSWRST; // release serial controller out of reset
}

char I2CSendBytes(char address, char* txBuffer, char numBytes)
{
char bytesSent; // counts number of bytes sent
char errorCode; // holds error code to return

errorCode = 0; // preset error code to no error

UCB1CTL1 |= UCTR; // set to transmitter mode
UCB1IFG &= ~UCTXIFG; // Clear USCI_B1 TX int flag
UCB1I2CSA = address; // load address byte
timeout = 0; // initialize timeout counter
while ((UCB1CTL1 & UCTXSTP) && (!errorCode)) // wait for stop bit to have occured
{
if(timeout > I2C_SEND_TIMEOUT)
{
errorCode = I2C_RX_TIMEOUT_1;
}
}
UCB1CTL1 |= UCTXSTT; // transmit start condition
bytesSent = 0; // init counter
while(bytesSent < numBytes)
{
timeout = 0; // initialize timeout counter
while (((UCB1IFG & UCTXIFG) == 0) && (!errorCode)) // wait for transmit buffer to be ready
{
if(UCB1IFG & UCNACKIFG)
{
errorCode = I2C_NACK_RECEIVED;
}
if(timeout > I2C_SEND_TIMEOUT)
{
errorCode = I2C_TX_TIMEOUT_1;
}
}
UCB1IFG &= ~UCTXIFG; // Clear USCI_B0 TX int flag
UCB1TXBUF = txBuffer[bytesSent]; // load data byte
bytesSent++; // increment bytes sent counter
}
while (((UCB1IFG & UCTXIFG) == 0) && (!errorCode)) // wait for transmit buffer to be ready
{
if(timeout > I2C_SEND_TIMEOUT)
{
errorCode = I2C_TX_TIMEOUT_2;
}
}
UCB1IFG &= ~UCTXIFG; // Clear USCI_B0 TX int flag
if(errorCode)
{
UCB1CTL1 |= UCSWRST; // hold serial controller in reset
UCB1CTL1 &= ~UCSWRST; // release serial controller out of reset
}
else
{
UCB1CTL1 |= UCTXSTP; // transmit stop condition
}
return errorCode;
}
