RFConfig-nrf24e1

Hi could anyone explain what the below means involving the configuration of the nrf24e1 radio:

transmitter:

const RFConfig txconf =
{
    15,
    0x08, 0x08, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
    0x12, 0x34, 0x56, 0x78, 0x83, 0x6c, 0x04
};

Receiver:

};

const RFConfig rxconf =
{
    15,
    0x08, 0x08, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
    0x87, 0x65, 0x43, 0x21, 0x83, 0x6c, 0x05
};

I am of the belief it is for the configuring of shockburst and payload (from manual) but am unsure what the numbers are for (in decimal-seems to not be obvious as what they are for)

your knowledgable help is greatly appreciated.

Jon
