Register 0—N Register Comments
• The Tx/Rx bit (R0_DB27) configures the part in Tx or Rx mode and also controls the state of the internal Tx/Rx switch.
•
• If operating in 433 MHz band with the VCO band bit set, the desired frequency, F
operating frequency, due to removal of the divide-by-2 stage in feedback path.
