i am a newbie to TM4C123G

Could anyone please guide me if my code is correct

I am trying to use PD6 to receive card number from a RDM6300 RFID Card reader

Baud rate: 9600

8 Bits

1 stop bit

No parity

FIFO enabled

Interrupt at 7/8 full

following is my code:

#define UART_FR_RXFE            0x00000010  // UART Receive FIFO Empty
#define UART_LCRH_WLEN_8        0x00000060  // 8 bit word length
#define UART_LCRH_FEN           0x00000010  // UART Enable FIFOs
#define UART_CTL_UARTEN         0x00000001  // UART Enable

void UART_Init(void){
SYSCTL_RCGCUART_R |= 0x04;            // activate UART2
SYSCTL_RCGCGPIO_R |= 0x08;            // activate port D
while((SYSCTL_PRGPIO_R&0x08) == 0);
UART2_CTL_R = 0;      // disable UART
UART2_IBRD_R = 104;      /* for 9600 baud rate, integer = 104 */
UART2_FBRD_R = 11;       /* for 9600 baud rate, fractional = 11*/
UART2_LCRH_R = (UART_LCRH_WLEN_8|UART_LCRH_FEN);
UART2_CTL_R |= UART_CTL_UARTEN;       // enable UART
GPIO_PORTD_AFSEL_R |= 0x40;           // enable alt funct on PD6
GPIO_PORTD_DEN_R |= 0x40;             // enable digital I/O on PD6
GPIO_PORTD_PCTL_R = (GPIO_PORTD_PCTL_R&0x0F000000)+0x01000000;  // configure PD6 as UART
GPIO_PORTD_AMSEL_R = 0;          // disable analog functionality on PD
 
  // enable interrupt
  UART2_ICR_R &= 0x10;  // Clear receive interrupt
  UART2_IM_R  = 0x10;
  NVIC_EN1_R =1;
  NVIC_PRI8_R = (NVIC_PRI8_R&0xFFFFFFF0)|0x0000000A; // (g) priority 0                                     
}

void UART2_Handler( void )
                {
                    char tag_arr[13];
                    uint16_t i=0;
                    unsigned char rx_data = 0;
                    UART2_ICR_R &= 0x10; // Clear receive interrupt
                    rx_data = UART2_DR_R ; // get the received data byte
                    LCD4bits_Data (rx_data);
            tag_arr[i]=rx_data;
            i++;
                }
