Description

PLL control register

Fields

LOCK

PLL lock status flag

0 (UNLOCKED): The frequency difference of fREF and fDIV is greater than allowed. The VCO part of the PLL can not lock on a target frequency

1 (LOCKED): The frequency difference of fREF and fDIV is small enough to enable a stable VCO operation

RESLD

Restart lock detection

0 (NO): No effect

1 (RESET): Reset lock flag and restart lock detection

OSCDISC

Oscillator disconnect

0 (CONNECTED): Oscillator is connected to the PLL

1 (DISCONNECTED): Oscillator is disconnected to the PLL

VCOBYP

PLL VCO bypass mode select

0 (NORMAL): Normal (or free running) operation (default)

1 (PRESCALER): Prescaler mode; VCO is bypassed (PLL output clock is derived from input clock divided by K1-divider)

NDIV

PLL N-divider

0 (48): N = 48

1 (50): N = 50

2 (51): N = 51

3 (52): N = 52

4 (54): N = 54

5 (60): N = 60

6 (67): N = 67

7 (72): N = 72

8 (75): N = 75

9 (78): N = 78

10 (80): N = 80

11 (88): N = 88

12 (90): N = 90

13 (94): N =94

14 (100): N = 100

15 (160): N = 160
