PRODUCT SPECIFICATION
nRF2401 Single Chip 2.4 GHz Radio Transceiver
Configuration Word overview
The configuration word is shifted in MSB first on positive CLK1 edges. New
configuration is enabled on the falling edge of CS.
NOTE.
On the falling edge of CS, the nRF2401 updates the number of bits actually shifted in
during the last configuration.
Ex:
If the nRF2401 is to be configured for 2 channel RX in ShockBurst™, a total of 120
bits must be shifted in during the first configuration after VDD is applied.
Once the wanted protocol, modus and RF channel are set, only one bit (RXEN) is
shifted in to switch between RX and TX.
