Type Description
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. 1: TX FIFO full. 0:
Available locations in TX FIFO.
08 OBSERVE_TX Transmit observe register
PLOS_CNT 7:4 0 R Count lost packets. The counter is
overflow protected to 15, and discontinue
at max until reset. The counter is reset by
writing to RF_CH. See page 14 and 17.
ARC_CNT 3:0 0 R Count resent packets. The counter is reset
when transmission of a new packet starts.
See page 14.
09 CD
Reserved 7:1 000000 R
CD 0 0 R Carrier Detect. See page 17.
0A RX_ADDR_P0 39:0
0xE7E7E7E7E7
R/W Receive address data pipe 0. 5 Bytes
maximum length. (LSByte is written first.
Write the number of bytes defined by
SETUP_AW)
0B RX_ADDR_P1 39:0
0xC2C2C2C2C2
R/W Receive address data pipe 1. 5 Bytes
maximum length. (LSByte is written first.
Write the number of bytes defined by
SETUP_AW)
0C RX_ADDR_P2 7:0 0xC3 R/W Receive address data pipe 2. Only LSB.
MSBytes will be equal to
RX_ADDR_P1[39:8]
0D RX_ADDR_P3 7:0 0xC4 R/W Receive address data pipe 3. Only LSB.
MSBytes will be equal to
RX_ADDR_P1[39:8]
0E RX_ADDR_P4 7:0 0xC5 R/W Receive address data pipe 4. Only LSB.
MSBytes will be equal to
RX_ADDR_P1[39:8]
0F RX_ADDR_P5 7:0 0xC6 R/W Receive address data pipe 5. Only LSB.
MSBytes will be equal to
RX_ADDR_P1[39:8]
10 TX_ADDR 39:0
0xE7E7E7E7E7
R/W Transmit address. Used for a PTX device
only. (LSByte is written first)
Set RX_ADDR_P0 equal to this address
to handle automatic acknowledge if this is
a PTX device with Enhanced
ShockBurst™ enabled. See page 14.
11 RX_PW_P0
Reserved 7:6 00 R/W Only '00' allowed
RX_PW_P0 5:0 0 R/W Number of bytes in RX payload in data
pipe 0 (1 to 32 bytes).
0 Pipe not used
1 = 1 byte
…
32 = 32 bytes
12 RX_PW_P1
Reserved 7:6 00 R/W Only '00' allowed
RX_PW_P1 5:0 0 R/W Number of bytes in RX payload in data
pipe 1 (1 to 32 bytes).
0 Pipe not used
