1) These are the same.

2) As you say you have data pipe information in addition in the status register. So you should check that.

Just to clarify. The apparent double representations in the nRF24LE1 are here:

STATUS bit 0 is TX_FULL

and

FIFO_STATUS bit 5 is "also?" TX_FULL

STATUS bit 3:1 RX_P_NO is RX_EMPTY

and

FIFO_STATUS bit 0 is "also?" RX_EMPTY

I am just wondering if they are exactly the same or if there could in some circumstances be a reason to read from the STATUS register instead of the FIFO_STATUS register, or vice versa.
