int main(void)
{
  init();
  
  uint8_t btn0_nstate;                              // Store new (current) state of button 0
  uint8_t btn1_nstate;                              // Store new (current) state of button 1
  uint8_t btn0_ostate = nrf_gpio_pin_read(BUTTON0); // Store old (previous) state of button 0
  uint8_t btn1_ostate = nrf_gpio_pin_read(BUTTON1); // Store old (previous) state of button 1
  
  while(true)
  {
    uint8_t btns = 0;
    btn0_nstate = nrf_gpio_pin_read(BUTTON0);
    btn1_nstate = nrf_gpio_pin_read(BUTTON1);

    {
      btns |= 2;
    }
   
    btn0_ostate = btn0_nstate;
    btn1_ostate = btn1_nstate;
   
    // Place the read buttons in the payload, enable the radio and
    // send the packet:
   // packet[0] = 1;
    NRF_RADIO->EVENTS_READY = 0U;
    NRF_RADIO->TASKS_TXEN = 1U;
    while (NRF_RADIO->EVENTS_READY == 0U)
    {
    }
    NRF_RADIO->TASKS_START = 1U;
    NRF_RADIO->EVENTS_END = 0U;  
    while(NRF_RADIO->EVENTS_END == 0U)
    {
    }
    NRF_RADIO->EVENTS_DISABLED = 0U;
    // Disable radio
    NRF_RADIO->TASKS_DISABLE = 1U;
    while(NRF_RADIO->EVENTS_DISABLED == 0U)
    {
    }
  }
}

此代码为nrf51822 demo代码，代码不能将TASKS_TXEN寄存器赋值？
