Bits 3:2 – RTN2[1:0] Resistor Tuning 2 Bit
RTN2[1:0] is used for 2-bit
resistor calibration.
Bits 1:0 – CTN2[1:0] Capacitor Tuning 2 Bit
CTN2[1:0] is used for the
2-bit capacitor calibration. Both calibration values are stored in the
factory-locked EEPROM. The values must be copied to the tuning register before using
the RF front end. Firmware does this by default.
