Fig. 52 Structure of frequency synthesizer control register
Frequency synthesizer control register (address 006C16)
FSC
Frequency synthesizer enable bit (FSE)
0: Disabled
1: Enabled
Fix to “00”.
Frequency synthesizer input bit (FIN)
0: f(XIN)
1: f(XCIN)
Reserved bit (“0” at read/write)
LPF current control (CHG1, CHG0) (Note)
b6b5
0 0: Not available
0 1: Low current
1 0: Intermediate current (recommended)
1 1: High current
Frequency synthesizer lock status bit
0: Unlocked
1: Locked
0
Note: Bits 6 and 5 are set to (bit 6, bit 5) = (1, 1) at reset.
When using the frequency synthesizer, we recommend to set to (bit 6, bit 5)
= (1, 0) after locking the frequency synthesizer.
