B7 .......................Selection of how to control General purpose driver 1.
0: Control register CR5-B0 1: GP1 is controlled by a sign bit of the receiver.
B6 .......................Not used
B5 .......................Power down control for Regulator 2
0: Power down
1: Power on
When using this data, set the RG2PDN pin at a “L” level.
B4 .......................Power down control for Regulator 1
0: Power down
1: Power on
When using this data, set the RG1PDN pin at a “L” level.
B3, B2, B1, B0 ....General purpose driver control
0: Off (high impedance) 1: On (“L” output)

B7 .............................. Transmit side voice/silence detection 0: silence 1: voice detect
B6, B5........................ Transmit side silence detect level (indicator)
(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”.
