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
