programmable address bits (see Table 5)
programmable divider bits; N = N14
charge-pump current; CP = 0 = 60 A; CP = 1 = 280 A (default)
test bits (see Table 6); for normal operation T2 = 0, T1 = 0 and T0 = 1 (default)
reference divider ratio select bits (see Table 7)
tuning amplifier control bit; for normal operation OS = 0 and tuning voltage is ON (default);
when OS = 1 tuning voltage is OFF (high impedance)
PNP band switch buffers control bits; when BS
is ON
