nRF24LE1 Preliminary Product Specification
3.3.1.6
The following table
3.3.1.7
The timing information in this section relates to the transitions between modes and the timing for the rfce
bit. The transition from TX mode to RX mode or vice versa is the same as the transition from the standby
modes to TX mode or RX mode (130µs), as described in
Revision 1.1

This is the normal operating mode. After the packet is transmitted, the RF Transceiver enters
