X means that this bit is not set or reset at power-on reset.
The next six bits are written, when bit T/A = 1 in a write sequence.
The next six bits are written, when bit T/A = 0 in a write sequence.

T
At power on, the charge pump current is set to 580 A, the test bits T[2:0] are set to 110
which means that the charge pump is sinking current, the tuning voltage output is
disabled. The XTOUT buffer is on, driving the 4 MHz signal from the crystal oscillator and
all the ports are off. As a consequence, the high band is selected by default.
