UART not receiving more than 1 byte

Hi, i am trying to use LPUART0 with pin PTA2 - Rx and PTB1 - Tx where it should receives 10 bytes of data using the LPUARTn NXP S32K11x MATLAB Library Block.

The Uart Recieve block has 1 input and 1 output signal. where the input is size. which i have given as 10.

here, the C code generated is receiving only 1 byte even when i am sending 10 bytes together using UART terminal. On checking the code generated the buffer used to receive data is just a uint8 variable and not a array.

/*generated code by MATLAB*/

/* Block signals (default storage) */

typedef struct {

real_T UnitDelay; /* '<Root>/Unit Delay' */

real_T Input; /* '<S1>/Input' */

uint32_T LPUART_RxTx_ISR_o2; /* '<Root>/LPUART_RxTx_ISR' */

uint8_T LPUART_Receive; /* '<S1>/LPUART_Receive' */

} B_gpio_s32k11x_T;

LPUART_DRV_ReceiveData(0, &gpio_s32k11x_B.LPUART_Receive, 10U);

Please help me here with MBD. What changes i should do to get all 10 bytes at once.
