Frcvco
Bit 7
PwdnPLL
(0X0E[7])
0 = Xtal oscillator as system clock.
1 = forces VCO as system clock. This bit is set to 0 upon reset, PwdnPll = 1 or ENFE = 0.
Both PwdnPll and ENFE are delayed coming out of digital section to keep PLL alive long
enough to transition the system clock to crystal clock when Frcvco is reset by PwdnPLL or
ENFE.
(0X0E[6])
1 = forces Power down of PLL analog section.
0 = normal operation
(0X0E[5])
1 = PLL locked
0 = PLL not locked.
Bit 6
(Register00 bit7)
Force Vco as System clock Enable.
PLL Power down Enable Please refer to the Table 4.
PLL Lock indicator. Read only.
