Direct Mode
In direct mode the nRF2402/nRF2402G works like a traditional RF device. The data rate
must be 1Mbps ±200ppm, or 250kbps ±200ppm at low data rate setting, for the receiver
(nRF2402/nRF24E1) to detect the signals.
MCU interface pins: CE, DIN
1.
When application MCU has data to send, set CE high
2.
The nRF2402/nRF2402G RF front end is now immediately activated, and after
200
μ
s settling time, signal on the DIN pin will modulate the carrier directly.
3.
All RF protocol parts must hence be implemented in MCU firmware (preamble,
address and CRC).
Configuration Mode
In configuration mode a configuration word of up to 20 bits is downloaded to
nRF2402/nRF2402G. This is done through a simple 3-wire interface (CS, CLK and DIN).
For more information on configuration please refer to the nRF2402/nRF2402G device
configuration chapter, page13.
Power Down Mode
Power down mode is used to achieve very low current consumption. Effectively the chip is
disabled with minimal leakage current consumption, typically less than 200nA. Operating in
this mode when not transmitting data significantly increases battery lifetime.
Stand-By Mode
Stand by mode is used to achieve low current consumption. In this mode only a part of the
crystal oscillator is running (12
μ
A) to guarantee a short start-up time. Operating in this mode
when not transmitting data increases battery lifetime while keeping start up delays short.
