mode.
You activate PRX mode by setting the CE pin high. The nRF24L01 enters RX mode and starts searching
for packets. If a packet is received and Auto Acknowledgement is enabled the nRF24L01 decides if this is
a new packet or a copy of a previously received packet. If the packet is new 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 acknowl-
edged with an ACK packet with payload, the TX_DS IRQ indicates that the PTX received the ACK packet
