VCO Power Down
(Active High)
When VCO Power Down is active, VCO does not oscillate. For getting out
of VCO Power Down, VCO initialization is required.
PLL Power Down
(Active High)
When PLL Power Down is active, digital circuits of PLL do not operate and
the charge pump circuit is disabled. Also Bypass Mode or Sleep
Mode(SCTRB[4]) register is set to high, PLL goes into sleep.
0
PLL output clock is 1/F(ck).
1
PLL output clock is the same of PLL input clock.
Bypass Mode
* VCO initialization
To ensure the proper operation of the PLL, the activation of VCO initialization signal is required
just after the deactivation of the VCO Power Down. During power-up sequence VCO initialization
signal is recommended for more than 100ns.
