programmable divider bits:
N = 2
charge pump current bit:
bit = 0: charge pump current = 50 µA or 125 µA
bit = 1: charge pump current = 250 µA (default) or 650 µA,
see Table 15 Charge pump current on page 49
tuning amplifier control bit:
bit = 0: enable V
PNP ports control bits
bit = 0: Port is inactive, high impedance state (default)
bit = 1: Port is active, V
Address selection bits, see Table 10 Address selection on page 47
test bits, see Table 11 Test modes on page 47
reference divider bits, see Table 12 Reference divider ratios on page 48
