DESCRIPTION
acknowledge
programmable address bits (see Table 5)
programmable divider bits; N = N14 × 214 + N13 × 213 + ... + N1 × 2 + N0
charge-pump current; CP = 0 = 60 µA; CP = 1 = 280 µA (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 BSn = 0 buffer n is OFF; when BSn = 1 buffer n
is ON
