State | Comment |

P_ON | This state is reached only during power up of the radio transceiver. If this state is left once, it will be reached only with the next power up. |
BUSY_TX | This state is reached during a frame transmission in basic operating mode. |
BUSY_RX | This state is reached during a frame reception in basic operating mode. |
BUSY_TX_ARET | This state is reached during a frame transmission in TX_ARET mode. |
BUSY_RX_AACK | This state is reached during a frame reception in RX_AACK mode. |
BUSY_RX_AACK_NOCLK | This state is reached during frame reception in RX_AACK mode, while TRX_PIN_SLP_TR is HIGH. |
STATE_TRANSITION [0x1f] | This state means, that an internal transaction of the radio transceiver is in progress and the status needs to be read another time, in order to obtain a valid result. |

(BUSY_DEFAULT) | This is a pseudo state. It is a symbol for the default fallback state for any of the busy states. BUSY_TX => PLL_ON / BUSY_RX => RX_ON / BUSY_TX_ARET => TX_ARET_ON / BUSY_RX_AACK => RX_AACK_ON |
(BUSY_RX_AACK_MATCH) | pseudo state for BUSY_RX_AACK / BUSY_RX_AACK_NOCLK when the received frame does match the address filter and has an valid FCS. In this case the interrupt TRX_IRQ_TRX_END is generated.. |
(BUSY_RX_AACK_NOMATCH) | pseudo state for BUSY_RX_AACK / BUSY_RX_AACK_NOCLK when the received frame does not match the address filter or/and has an invalid FCS. In this case no interrupt TRX_IRQ_TRX_END is generated. |
