Accuracy is
±0.03VCC. Bit BS5 must be set to logic 0 to disable the BS5 output port. The BS5 output port
uses the same pin as the ADC and can not be used when the ADC is in use.
8.3 Status at power-on reset
At power on or when the supply voltage drops below approximately 2.85 V (at
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.

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.
[3]
The next six bits are written, when bit T/A = 0 in a write sequence.
