UART receive datas will be lost on CC254x

$

I only receive datas from UART by interrupt.

a. Initialize UART

void scc_init(void)
{
	PERCFG &= ~(1 << 0);
	P0SEL |= (1 << 2) | (1 << 3);
	U0CSR |= (1 << 7);
	U0GCR |= 11;
	U0BAUD |= 216;

	UTX0IF = 0;
	URX0IF = 0;
	U0CSR |= (1 << 6);
	URX0IE = 1;
	EA = 1;
	
	this_rxbuf_wi = 0;	 
}

b. Receive datas

HAL_ISR_FUNCTION(this_urx0_isr, URX0_VECTOR)
{
	HAL_ENTER_ISR();
	
	URX0IF = 0;
	this_rxbuf[this_rxbuf_wi] = U0DBUF;
	
	if(++this_rxbuf_wi >= THIS_RXBUF_SIZE){
		  this_rxbuf_wi = 0;
	}
	
	HAL_EXIT_ISR();
}

Always lose data when testing, for example

a. I send [aa bb 0a 03 12 48 10 f3 7b 98 0d 0a] from PC

b. But only received [AA BB 03 48 F3 0D 0D 0A] at this_rxbuf on CC254X

Is there any wrong? Thanks!
