Accuracy is

. 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.

Status at Power-on reset
At power on or when the supply voltage drops below approximately 2.85 V (at T
amb
= 25
°
C), internal registers are set
according to Table 15.
At power on, the charge pump current is set to 580
μ
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 and the ALBC function 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.
The next six bits are written, when bit T/A = 0 in a write sequence.
