Read command and status registers. AAAAA =
5 bit Register Map Address
Write command and status registers. AAAAA = 5
bit Register Map Address
Executable in power down or standby modes
only.
Read RX-payload: 1 – 32 bytes. A read operation
always starts at byte 0. Payload is deleted from
FIFO after it is read. Used in RX mode.
Write TX-payload: 1 – 32 bytes. A write operation
always starts at byte 0 used in TX payload.
Flush TX FIFO, used in TX mode
Flush RX FIFO, used in RX mode
Should not be executed during transmission of
acknowledge, that is, acknowledge package will
not be completed.
Used for a PTX device
Reuse last transmitted payload. Packets are
repeatedly retransmitted as long as CE is high.
TX payload reuse is active until
W_TX_PAYLOAD or FLUSH TX is executed. TX
payload reuse must not be activated or deacti-
vated during package transmission
This write command followed by data 0x73 acti-
vates the following features:
A new ACTIVATE command with the same data
deactivates them again. This is executable in
power down or stand by modes only.
The R_RX_PL_WID, W_ACK_PAYLOAD, and
W_TX_PAYLOAD_NOACK features registers are
initially in a deactivated state; a write has no
effect, a read only results in zeros on MISO. To
activate these registers, use the ACTIVATE com-
mand followed by data 0x73. Then they can be
accessed as any other register in nRF24L01. Use
the same command and data to deactivate the
registers again.
Read RX-payload width for the top
R_RX_PAYLOAD in the RX FIFO.
Used in RX mode.
Write Payload to be transmitted together with
ACK packet on PIPE PPP. (PPP valid in the
range from 000 to 101). Maximum three ACK
packet payloads can be pending. Payloads with
same PPP are handled using first in - first out
principle. Write payload: 1– 32 bytes. A write
operation always starts at byte 0.
