PLLAC[3:0]. Default = 1100.
Refers to the lower 4-bit in the 9-BIT A-Counter. Remember that
the total 9-BIT value refers to the A-1 value.
PLLBC[3:0]. Default = 0100.
Register that sets the 4-BIT B-Counter.
PSC_MODE, Default = 1. Sets the Prescaler Dual Mode.
1: P = 16 Mode, with divide ratio of 16 or 17.
0: P = 8 Mode, with divide ratio of 8 or 9.
Default = 00
Absolutely not used.
PLLAC[8:4]. Default = 00000.
Refers to the upper 5-bit in the 9-BIT A-Counter. Remember that
the total 9-BIT value refers to the A-1 value.
PLLRC[7:0]. Default = 00001111.
Refers to the lower 8-bit in the 10-BIT A-Counter. Remember
that the total 10-BIT value refers to the A-1 value.
LOCK_LEN. Default = 110.
Lock output set register sets the lock output by detemining the
time cut-line for level of PLL & VCO stabilization Phases must
match duringTCXO*2
(M+13)
for lock.
PD_MODE. Default = 1
Decides the polarity of the phase comparator gain (+ or -1).
0: Negative VCO gain (-Kv)
1: Normal operation.
Default = 00, Absolutely not used.
