Test mode bits
Notes
1. This is the default mode at Power-on reset.
2. The ADC input cannot be used when these test modes are active; see Section 8.2.3 for more information.
BIT
DESCRIPTION
MA1 and MA0
programmable address bits (see Table 6)
R/W
logic 0 for write mode
N14 to N0
programmable divider bits: N = N14
× 214 + N13 × 213 + ... + N1 × 21 +N0
CP
charge pump current control bit:
logic 0: charge pump current is 60
A
logic 1: charge pump current is 280
A (at power-on)
T2, T1 and T0
test bits (see Table 7)
RSA and RSB
reference divider ratio select bits (see Table 8)
OS
tuning amplier control bit:
logic 0: tuning voltage is ‘on’ (during normal operating)
logic 1: tuning voltage is ‘off’; high-impedance output of pin VT (at power-on)
PVHFL, PVHFH, PUHF and FMST
PMOS ports control bits:
