CC2530 P0.4和P0.5工作异常

基于3.0.2协议栈例程，使用了2530的串口0（P0.2和P0.3）

P0.4和P0.5作为普通IO使用，当串口0使用的时候P0.4和P0.5作为IO工作就异常了，

流控制已经关了uartConfig.flowControl = FALSE;请问可能是什么原因?

P0SEL &= ~BV(4);
P0SEL &= ~BV(5);
P0DIR |= BV(4);
P0DIR |= BV(5);
P0_4 = 0;
P0_5 = 0;

把uartConfig.intEnable也設置成FALSE看看

uartConfig.intEnable設置成FALSE还是一样的现象，
P0_5接的是LED，LED一直闪烁，当串口没数据的时候，P0_5是正常的

若是可以的话，请给出您的串口初始化代码

void initUart0()
{
  halUARTCfg_t uartConfig;
  
  /* Initialize APP ID */
  App_TaskID = 0;
  
  uartConfig.configured = TRUE;
  uartConfig.baudRate = HAL_UART_BR_4800;//HAL_UART_BR_9600;
  uartConfig.flowControl = FALSE;
  uartConfig.flowControlThreshold = 256;
  uartConfig.rx.maxBufSize = 512;//默认128;
  uartConfig.tx.maxBufSize = 512;//默认128;
  uartConfig.idleTimeout = 6; 
  uartConfig.intEnable = FALSE; 
  uartConfig.callBackFunc = uartRxCb;
  HalUARTOpen (HAL_UART_PORT_0, &uartConfig);
}
void uartRxCb( uint8 port, uint8 event )
{
  while (Hal_UART_RxBufLen(port))
  {
    // Read one byte from UART to ch
    HalUARTRead (port, &UartDataBuf[Head++], 1);
  }
}

那HAL_UART /HAL_UART_ISR以及 HAL_UART_DMA您是如何设置的呢？
