MSP-EXP430FR6989: Uart_A0_ and driverlib example

From Resource explorer, I import the msp430fr69xx_eusci_uart_standard_transceiver C project. I jumper P2.- and P2.1 pins to RX and TX on the launchpad and from the terminal, I can send and receive the correct character. 

Then I import the eusci_a_uart_ex1_loopbackAdvanced project (driverlib)  I copy the interrupt functions from the above project but I got many errors on the serial port.

I have some questions.

a) the code below from the working project

// Configure UART
        P2SEL0 |= BIT0 | BIT1;                    // USCI_A0 UART operation
        P2SEL1 &= ~(BIT0 | BIT1);
UCA0CTLW0 |= UCSSEL__ACLK;               // CLK = ACLK
        // Baud Rate calculation
        // 32768/(9600) = 3.4133
        // Fractional portion = 0.4133
        // Use Table 24-5 in Family User Guide
        UCA0BR0 = 3;                             // 32768/9600
        UCA0BR1 = 0;
        UCA0MCTLW |= 0x9200;    //0x9200 is UCBRSx = 0x92
        UCA0CTLW0 &= ~UCSWRST;                    // Initialize eUSCI
        UCA0IE |= UCRXIE;                         // Enable USCI_A0 RX interrupt

As I can see the code below -using the driverlib- do the same but it has too many errors on the serial port

 GPIO_setAsPeripheralModuleFunctionInputPin(
    GPIO_PORT_P2,
    GPIO_PIN0 + GPIO_PIN1,
    GPIO_SECONDARY_MODULE_FUNCTION
    );
// Configure UART
    EUSCI_A_UART_initParam param = {0};
    param.selectClockSource = EUSCI_A_UART_CLOCKSOURCE_ACLK;
    param.clockPrescalar = 3;
    param.firstModReg = 0;
    param.secondModReg = 0x92;  // the source code has the value 92 not 0x92     is it a typograhic error?
    param.parity = EUSCI_A_UART_NO_PARITY;
    param.msborLsbFirst = EUSCI_A_UART_LSB_FIRST;
    param.numberofStopBits = EUSCI_A_UART_ONE_STOP_BIT;
    param.uartMode = EUSCI_A_UART_MODE;
    param.overSampling = EUSCI_A_UART_LOW_FREQUENCY_BAUDRATE_GENERATION;

    if (STATUS_FAIL == EUSCI_A_UART_init(EUSCI_A0_BASE, &param)) {
        return;
    }
    EUSCI_A_UART_enable(EUSCI_A0_BASE);
    EUSCI_A_UART_clearInterrupt(EUSCI_A0_BASE,      EUSCI_A_UART_RECEIVE_INTERRUPT);

    // Enable USCI_A0 RX interrupt
    EUSCI_A_UART_enableInterrupt(EUSCI_A0_BASE,
                                 EUSCI_A_UART_RECEIVE_INTERRUPT);                     // Enable interrupt

the rest of the code is the same at two projects

    __enable_interrupt();

    while (1)
    {
      
        __bis_SR_register(LPM3_bits + GIE);       // Since ACLK is source, enter LPM3, interrupts enabled
    }
}

{
  switch(__even_in_range(UCA0IV, USCI_UART_UCTXCPTIFG))
  {
    case USCI_NONE: break;
    case USCI_UART_UCRXIFG:
      while(!(UCA0IFG&UCTXIFG));
      UCA0TXBUF = UCA0RXBUF;
     // P1OUT ^=BIT0;
      __no_operation();
      break;
    case USCI_UART_UCTXIFG: break;
    case USCI_UART_UCSTTIFG: break;
    case USCI_UART_UCTXCPTIFG: break;
  }
}

b) GPIO_setAsPeripheralModuleFunctionInputPin at
driverlib ver  2.91.13.01  the  accepts 2 params

can you give me more information about that?

c) I want to use Uart_A1 ( P3.4 and P3.5 ) which is the piece of code to do the same for P3.4 and P3.5 with the drivelib?
