Concatenated code for output power backoff for TX0, TX1, TX2
Bit Description
b7:0 TX0 output power back off
b15:8 TX1 output power back off
b23:16 TX2 output power back off
b31:24 Reserved
This field defiens how much the transmit power should be reduced from the maximum
1 LSB = 1 dB
If TX power boot time calibration is disabled then only 0dB back off is
supported. 0dB back-off corresponds to typically 12dBm power level.
In IWR6843 (both ES1.0 and ES2.0), uncalibrated back-off in 3dB steps is
supported in cases where the TX power calibration is disabled.

txPhaseShifter
Concatenated phase shift for TX0/1/2,
Bit Description
b1:0 Reserved(set to 0b00)
b7:2 TX0 phase shift value
1 LSB = 360/2^6 = 5.625 degrees
b9:8 Reserved(set to 0b00)
b15:10 TX1 phase shift value
1 LSB = 360/2^6 = 5.625 degrees
b17:16 Reserved(set to 0b00)
b23:18 TX2 phase shift value
1 LSB = 360/2^6 = 5.625 degrees
b31:24 Reserved(set to 0b00)
This field defines the additional phase shift to be introduced on each
transmitter output. In IWR6843 ES1.0, only 0 degree phase is supported.

b5:0 Code for Rx VGA gain
1 LSB = 1 dB
Valid values: all even values from 24 to 52
b7:6 Code for RF gain target (Not applicable for IWR6843 ES1.0,
RF gain is fixed to 34dB).
For xWR1243/xWR1443/xWR1642/xWR1843: 00 - 30 dB
01 - 34 dB
10 - RESERVED
11 - 26 dB
For IWR6843 ES 2.0: 00 - 30 dB
01 - 33 dB
