CC2530无线中断接收问题

各位大虾，小弟初学zigbee，现在做了一个无线串口，问题是每次都只能进一次RF的接收中断，数据是正确的，接收到数据之后，连串口接收中断都进不去，全局只用了RF接收和串口接收中断，代码如下（两个班子烧同样的代码）：

#include "cmd.h"
#include "adc.h"

#define uint unsigned int
#define uchar unsigned char

#define Fosc 32000000
//#define datalen 1//20440

#define UART_CMD_LEN 3

void Delay(uint temp);
