nRF24LE1 Preliminary Product Specification
the payload is made available in the RX FIFO and the RX_DR IRQ is asserted. If the last received packet
from the transmitter is acknowledged with an ACK packet with payload, the TX_DS IRQ indicates that the
PTX received the ACK packet with payload. If the No_ACK flag is not set in the received packet, the PRX
enters TX mode. If there is a pending payload in the TX FIFO it is attached to the ACK packet. After the
ACK packet is transmitted, the RF Transceiver returns to RX mode.
A copy of a previously received packet might be received if the ACK packet is lost. In this case, the PRX
discards the received packet and transmits an ACK packet before it returns to RX mode.

MultiCeiver™ is a feature used in RX mode that contains a set of six parallel data pipes with unique add-
resses. A data pipe is a logical channel in the physical RF channel. Each data pipe has its own physical
address (data pipe address) decoding in the RF Transceiver.
The RF Transceiver configured as PRX (primary receiver) can receive data addressed to six different data
pipes in one frequency channel as shown in
be configured for individual behavior.
Up to six RF Transceivers configured as PTX can communicate with one RF Transceiver configured as
PRX. All data pipe addresses are searched for simultaneously. Only one data pipe can receive a packet at
a time. All data pipes can perform Enhanced ShockBurst™ functionality.
The following settings are common to all data pipes:
