R/W
Data Ready RX FIFO interrupt
Asserted when new data arrives RX FIFO
Write 1 to clear bit.
TX_DS
5
0
R/W
Data Sent TX FIFO interrupt
Asserted when packet transmitted on TX.
If AUTO_ACK is activated, this bit is set
high only when ACK is received.
Write 1 to clear bit.
Maximum number of TX retransmits
MAX_RT

0
R/W
interrupt
Write 1 to clear bit. If MAX_RT is
asserted it must be cleared to enable
further communication.
RX_P_NO

111
R
Data pipe number for the payload
available for reading from RX_FIFO
000-101: Data Pipe Number
110: Not used
111: RX FIFO Empty
TX_FULL
0
0
R
TX FIFO full flag.

PLOS_CNT
7:4
0000
R
Count lost packets. The counter is
overflow protected to 15, and discontinues
at max until reset. The counter is reset by
writing to RF_CH.
ARC_CNT
3:0
0000
R
Count retransmitted packets. The counter
is reset when transmission of a new packet
starts.
