    I mean,i want to use two IOs to control the TX _EN and RX_EN pins of PA.When the transiceiver is in TX mode,i enable the TX_EN pin and disable the RX_EN pin of PA,and when the transiceiver is in RX mode,i should disable the TX_EN pin and enable the RX_EN pin. The question is how do i know the states of transiverver when the NRF51822 runs BLE stack? Can i read the register named radio_states to know the states of the NRF51822 then i control the TX_EN and RX_EN pin?

    Could you emploees give me a clear solution,if you can give me a reference,i will preciate.

    Than you very much!
