Table 7 RF operational settings
RX2_EN:
Logic 0: One channel receive
Logic 1: Two channels receive
NOTE
In two channels receive, the TRW-24G receives on two, separate frequency channels
simultaneously. The frequency of receive channel 1 is set in the configurati on word
B[7-1], receive channel 2 is always 8 channels (8 MHz) above receive channel 1.
Bit 14:
Communication Mode:
Logic 1: operates in ShockBurstTM mode
Bit 13:
RF Data Rate:
Logic 0: 250 kbps
Logic 1: 1 Mbps
NOTE
Utilizing 250 kbps instead of 1 Mbps will improve the receiver sensitivity by 10 dB. 1
Mbps requires 16MHz crystal.
Bit 12-10:
XO_F: Selects the crystal frequency to be used. Default to be 16MHz.
