PLL N-Divider
This is a PASSWD protected bit. When the protection
scheme (see
) is activated (default), this bit
cannot be written directly.

PLL VCO Bypass Mode Select
This bit is cleared by hardware when PLL switches to
freerunning mode.
When the bit value changes from 0 to 1, bit OSCDISC = 0.
0
B
Normal (or freerunning) operation (default)
1
B
Prescaler Mode; VCO is bypassed (PLL output clock is
derived from input clock divided by K1-divider)
OSCDISC

rw
Oscillator Disconnect
By default after power-on reset, PLL is running in
Freerunning Mode (osc is disconnected).
0
B
Oscillator is connected to the PLL
1
B
Oscillator is disconnected to the PLL.

Restart Lock Detection
Setting this bit will reset the PLL lock status flag and
restart the lock detection. This bit will be automatically
reset to 0 and thus always be read back as 0.
0
B
No effect.
1
B
Reset lock flag and restart lock detection.
