0: Control register CR5-B0 1: GP1 is controlled by a sign bit of the receiver.
0: Power down
When using this data, set the RG2PDN pin at a “L” level.
0: Power down
When using this data, set the RG1PDN pin at a “L” level.
0: Off (high impedance)
0
(0,0): Below –50 dBm0 (0,1): –40 to –50 dBm0
(1,0): –30 to –40 dBm0 (1,1): Above –30 dBm0
Note: These outputs are enabled only when the VOX (CR6-B7) = “1”.
TX Noise
If B7 is set to a logic “1”, B3 should be set to a logic “1”.
