nRF24LE1 Preliminary Product Specification
The W_REGISTER and R_REGISTER commands operate on single or multi-byte registers. When accessing
multi-byte registers read or write to the MSBit of LSByte first. You can terminate the writing before all bytes
in a multi-byte register are written, leaving the unwritten MSByte(s) unchanged. For example, the LSByte
of RX_ADDR_P0 can be modified by writing only one byte to the RX_ADDR_P0 register. The content of the
status register is always read to MISO after a high to low transition on CSN.

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 operation
Reuse last transmitted payload.
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.
Read RX payload width for the top
R_RX_PAYLOAD in the RX FIFO.
Note: Flush RX FIFO if the read value is larger
than 32 bytes.
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.
Used in TX mode. Disables AUTOACK on this
specific packet.
No Operation. Might be used to read the STATUS
register
have to be set.
