Table 10 Frequency channel + RX/TX setting

Bit 7-1:

RF_CH#: Sets the frequency channel the nRF2401 operates on.

The channel frequency in transmit is given by:

ChannelRF = 2400 MHz + RF_CH# ･1.0 MHz

RF_CH # : between 2400MHz and 2527MHz may be set.

The channel frequency in data channel 1 is given by:

ChannelRF = 2400 MHz + RF_CH#･1.0 MHz (Receive at PIN#8)

RF_CH # : between 2400MHz and 2524MHz may be set.

Bit 0:

NOTE

The channels above 83 can only be utilized in certain territories (ex: Japan)

The channel frequency in data channel 2 is given by:

ChannelRF = 2400 MHz + RF_CH#･1.0 MHz + 8MHz

(Receive at PIN#4)

RF_CH # : between 2408MHz and 2524MHz may be set.

Set active mode:

Logic 0: transmit mode

Logic 1: receive mode
